In the ea_get function in fs/jfs/xattr.c in the Linux kernel through 4.17.1, a memory corruption bug in JFS can be triggered by calling setxattr twice with two different extended attribute names on the same file. This vulnerability can be triggered by an unprivileged user with the ability to create files and execute programs. A kmalloc call is incorrect, leading to slab-out-of-bounds in jfs_xattr.

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - In the ea_get function in fs/jfs/xattr.c in the Linux     kernel through 4.17.1, a memory corruption bug in JFS     can be triggered by calling setxattr twice with two     different extended attribute names on the same file.
    This vulnerability can be triggered by an unprivileged     user with the ability to create files and execute     programs. A kmalloc call is incorrect, leading to     slab-out-of-bounds in jfs_xattr.(CVE-2018-12233i1/4%0

  - The spectre_v2_select_mitigation function in     arch/x86/kernel/cpu/bugs.c in the Linux kernel before     4.18.1 does not always fill RSB upon a context switch,     which makes it easier for attackers to conduct     userspace-userspace spectreRSB     attacks.(CVE-2018-15572i1/4%0

  - Race condition in the queue_delete function in     sound/core/seq/seq_queue.c in the Linux kernel before     4.4.1 allows local users to cause a denial of service     (use-after-free and system crash) by making an ioctl     call at a certain time.(CVE-2016-2544i1/4%0

  - A flaw was found in the Linux kernel's implementation     of BPF in which systems can application can overflow a     32 bit refcount in both program and map refcount. This     refcount can wrap and end up a user after     free.(CVE-2016-4558i1/4%0

  - Interpretation conflict in     drivers/md/dm-snap-persistent.c in the Linux kernel     through 3.11.6 allows remote authenticated users to     obtain sensitive information or modify data via a     crafted mapping to a snapshot block     device.(CVE-2013-4299i1/4%0

  - The imon_probe function in drivers/media/rc/imon.c in     the Linux kernel through 4.13.11 allows local users to     cause a denial of service (NULL pointer dereference and     system crash) or possibly have unspecified other impact     via a crafted USB device.(CVE-2017-16537i1/4%0

  - A cross-boundary flaw was discovered in the Linux     kernel software raid driver. The driver accessed a     disabled bitmap where only the first byte of the buffer     was initialized to zero. This meant that the rest of     the request (up to 4095 bytes) was left and copied into     user space. An attacker could use this flaw to read     private information from user space that would not     otherwise have been accessible.(CVE-2015-5697i1/4%0

  - The parse_hid_report_descriptor function in     drivers/input/tablet/gtco.c in the Linux kernel before     4.13.11 allows local users to cause a denial of service     (out-of-bounds read and system crash) or possibly have     unspecified other impact via a crafted USB     device.(CVE-2017-16643i1/4%0

  - A flaw was found in the Linux kernel which could cause     a kernel panic when restoring machine specific     registers on the PowerPC platform. Incorrect     transactional memory state registers could     inadvertently change the call path on return from     userspace and cause the kernel to enter an unknown     state and crash.(CVE-2015-8845i1/4%0

  - fs/namespace.c in the Linux kernel through 3.16.1 does     not properly restrict clearing MNT_NODEV, MNT_NOSUID,     and MNT_NOEXEC and changing MNT_ATIME_MASK during a     remount of a bind mount, which allows local users to     gain privileges, interfere with backups and auditing on     systems that had atime enabled, or cause a denial of     service (excessive filesystem updating) on systems that     had atime disabled via a 'mount -o remount' command     within a user namespace.(CVE-2014-5207i1/4%0

  - The NFS2/3 RPC client could send long arguments to the     NFS server. These encoded arguments are stored in an     array of memory pages, and accessed using pointer     variables. Arbitrarily long arguments could make these     pointers point outside the array and cause an     out-of-bounds memory access. A remote user or program     could use this flaw to crash the kernel, resulting in     denial of service.(CVE-2017-7645i1/4%0

  - The time subsystem in the Linux kernel, when     CONFIG_TIMER_STATS is enabled, allows local users to     discover real PID values (as distinguished from PID     values inside a PID namespace) by reading the     /proc/timer_list file, related to the print_timer     function in kernel/time/timer_list.c and the
    __timer_stats_timer_set_start_info function in     kernel/time/timer.c.(CVE-2017-5967i1/4%0

  - A vulnerability was found in the Linux kernel where the     keyctl_set_reqkey_keyring() function leaks the thread     keyring. This allows an unprivileged local user to     exhaust kernel memory and thus cause a     DoS.(CVE-2017-7472i1/4%0

  - A flaw was found that can be triggered in     keyring_search_iterator in keyring.c if type-i1/4zmatch     is NULL. A local user could use this flaw to crash the     system or, potentially, escalate their     privileges.(CVE-2017-2647i1/4%0

  - The make_response function in     drivers/block/xen-blkback/blkback.c in the Linux kernel     before 4.11.8 allows guest OS users to obtain sensitive     information from host OS (or other guest OS) kernel     memory by leveraging the copying of uninitialized     padding fields in Xen block-interface response     structures, aka XSA-216.(CVE-2017-10911i1/4%0

  - Stack-based buffer overflow in the SET_WPS_IE IOCTL     implementation in wlan_hdd_hostapd.c in the WLAN (aka     Wi-Fi) driver for the Linux kernel 3.x and 4.x, as used     in Qualcomm Innovation Center (QuIC) Android     contributions for MSM devices and other products,     allows attackers to gain privileges via a crafted     application that uses a long WPS IE     element.(CVE-2015-0570i1/4%0

  - The net_ctl_permissions function in net/sysctl_net.c in     the Linux kernel before 3.11.5 does not properly     determine uid and gid values, which allows local users     to bypass intended /proc/sys/net restrictions via a     crafted application.(CVE-2013-4270i1/4%0

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Ubuntu 16.04 LTS / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3752-3 advisory.

  - The Linux Kernel versions 4.14, 4.15, and 4.16 has a null pointer dereference which can result in an out     of memory (OOM) killing of large mlocked processes. The issue arises from an oom killed process's final     thread calling exit_mmap(), which calls munlock_vma_pages_all() for mlocked vmas.This can happen     synchronously with the oom reaper's unmap_page_range() since the vma's VM_LOCKED bit is cleared before     munlocking (to determine if any other vmas share the memory and are mlocked). (CVE-2018-1000200)

  - Linux Kernel version 3.18 to 4.16 incorrectly handles an SG_IO ioctl on /dev/sg0 with     dxfer_direction=SG_DXFER_FROM_DEV and an empty 6-byte cmdp. This may lead to copying up to 1000 kernel     heap pages to the userspace. This has been fixed upstream in     https://github.com/torvalds/linux/commit/a45b599ad808c3c982fdcdc12b0b8611c2f92824 already. The problem has     limited scope, as users don't usually have permissions to access SCSI devices. On the other hand, e.g. the     Nero user manual suggests doing `chmod o+r+w /dev/sg*` to make the devices accessible. NOTE: third parties     dispute the relevance of this report, noting that the requirement for an attacker to have both the     CAP_SYS_ADMIN and CAP_SYS_RAWIO capabilities makes it virtually impossible to exploit. (CVE-2018-1000204)

  - The xfs_bmap_extents_to_btree function in fs/xfs/libxfs/xfs_bmap.c in the Linux kernel through 4.16.3     allows local users to cause a denial of service (xfs_bmapi_write NULL pointer dereference) via a crafted     xfs image. (CVE-2018-10323)

  - Linux kernel is vulnerable to a heap-based buffer overflow in the fs/ext4/xattr.c:ext4_xattr_set_entry()     function. An attacker could exploit this by operating on a mounted crafted ext4 image. (CVE-2018-10840)

  - A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause an out-of-bound access in     ext4_get_group_info function, a denial of service, and a system crash by mounting and operating on a     crafted ext4 filesystem image. (CVE-2018-10881)

  - The ext4_valid_block_bitmap function in fs/ext4/balloc.c in the Linux kernel through 4.15.15 allows     attackers to cause a denial of service (out-of-bounds read and system crash) via a crafted ext4 image     because balloc.c and ialloc.c do not validate bitmap block numbers. (CVE-2018-1093)

  - kernel drivers before version 4.17-rc1 are vulnerable to a weakness in the Linux kernel's implementation     of random seed data. Programs, early in the boot sequence, could use the data allocated for the seed     before it was sufficiently generated. (CVE-2018-1108)

  - A flaw was found affecting the Linux kernel before version 4.17. By mmap()ing a FUSE-backed file onto a     process's memory containing command line arguments (or environment strings), an attacker can cause     utilities from psutils or procps (such as ps, w) or any other program which makes a read() call to the     /proc/<pid>/cmdline (or /proc/<pid>/environ) files to block indefinitely (denial of service) or for some     controlled time (as a synchronization primitive for other attacks). (CVE-2018-1120)

  - In the Linux kernel 4.13 through 4.16.11, ext4_read_inline_data() in fs/ext4/inline.c performs a memcpy     with an untrusted length value in certain circumstances involving a crafted filesystem that stores the     system.data extended attribute value in a dedicated inode. (CVE-2018-11412)

  - The sr_do_ioctl function in drivers/scsi/sr_ioctl.c in the Linux kernel through 4.16.12 allows local users     to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact     because sense buffers have different sizes at the CDROM layer and the SCSI layer, as demonstrated by a     CDROMREADMODE2 ioctl call. (CVE-2018-11506)

  - In net/socket.c in the Linux kernel through 4.17.1, there is a race condition between fchownat and close     in cases where they target the same socket file descriptor, related to the sock_close and sockfs_setattr     functions. fchownat does not increment the file descriptor reference count, which allows close to set the     socket to NULL during fchownat's execution, leading to a NULL pointer dereference and system crash.
    (CVE-2018-12232)

  - In the ea_get function in fs/jfs/xattr.c in the Linux kernel through 4.17.1, a memory corruption bug in     JFS can be triggered by calling setxattr twice with two different extended attribute names on the same     file. This vulnerability can be triggered by an unprivileged user with the ability to create files and     execute programs. A kmalloc call is incorrect, leading to slab-out-of-bounds in jfs_xattr.
    (CVE-2018-12233)

  - In arch/x86/kvm/vmx.c in the Linux kernel before 4.17.2, when nested virtualization is used, local     attackers could cause L1 KVM guests to VMEXIT, potentially allowing privilege escalations and denial of     service attacks due to lack of checking of CPL. (CVE-2018-12904)

  - An issue was discovered in fs/xfs/libxfs/xfs_attr_leaf.c in the Linux kernel through 4.17.3. An OOPS may     occur for a corrupted xfs image after xfs_da_shrink_inode() is called with a NULL bp. (CVE-2018-13094)

  - The inode_init_owner function in fs/inode.c in the Linux kernel through 3.16 allows local users to create     files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and     is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a     plain file whose group ownership is that group. The intended behavior was that the non-member can trigger     creation of a directory (but not a plain file) whose group ownership is that group. The non-member can     escalate privileges by making the plain file executable and SGID. (CVE-2018-13405)

  - An integer overflow in the uvesafb_setcmap function in drivers/video/fbdev/uvesafb.c in the Linux kernel     before 4.17.4 could result in local attackers being able to crash the kernel or potentially elevate     privileges because kmalloc_array is not used. (CVE-2018-13406)

  - In the Linux Kernel before version 4.16.11, 4.14.43, 4.9.102, and 4.4.133, multiple race condition errors     when handling probe, disconnect, and rebind operations can be exploited to trigger a use-after-free     condition or a NULL pointer dereference by sending multiple USB over IP packets. (CVE-2018-5814)

  - In driver_override_store and driver_override_show of bus.c, there is a possible double free due to     improper locking. This could lead to local escalation of privilege with System execution privileges     needed. User interaction is not needed for exploitation. Product: Android Versions: Android kernel Android     ID: A-69129004 References: Upstream kernel. (CVE-2018-9415)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3754-1 advisory.

  - The ext4_fill_super function in fs/ext4/super.c in the Linux kernel through 4.9.8 does not properly     validate meta block groups, which allows physically proximate attackers to cause a denial of service (out-     of-bounds read and system crash) via a crafted ext4 image. (CVE-2016-10208)

  - The acpi_ns_terminate() function in drivers/acpi/acpica/nsutils.c in the Linux kernel before 4.12 does not     flush the operand cache and causes a kernel stack dump, which allows local users to obtain sensitive     information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a     crafted ACPI table. (CVE-2017-11472)

(CVE-2017-5549)

  - The ip6gre_err function in net/ipv6/ip6_gre.c in the Linux kernel allows remote attackers to have     unspecified impact via vectors involving GRE flags in an IPv6 packet, which trigger an out-of-bounds     access. (CVE-2017-5897)

  - The LLC subsystem in the Linux kernel before 4.9.13 does not ensure that a certain destructor exists in     required circumstances, which allows local users to cause a denial of service (BUG_ON) or possibly have     unspecified other impact via crafted system calls. (CVE-2017-6345)

  - The hashbin_delete function in net/irda/irqueue.c in the Linux kernel before 4.9.13 improperly manages     lock dropping, which allows local users to cause a denial of service (deadlock) via crafted operations on     IrDA devices. (CVE-2017-6348)

  - A flaw was found in the Linux kernel before version 4.12 in the way the KVM module processed the trap     flag(TF) bit in EFLAGS during emulation of the syscall instruction, which leads to a debug exception(#DB)     being raised in the guest stack. A user/process inside a guest could use this flaw to potentially escalate     their privileges inside the guest. Linux guests are not affected by this. (CVE-2017-7518)

  - The NFSv2/NFSv3 server in the nfsd subsystem in the Linux kernel through 4.10.11 allows remote attackers     to cause a denial of service (system crash) via a long RPC reply, related to net/sunrpc/svc.c,     fs/nfsd/nfs3xdr.c, and fs/nfsd/nfsxdr.c. (CVE-2017-7645)

  - Linux Kernel version 3.18 to 4.16 incorrectly handles an SG_IO ioctl on /dev/sg0 with     dxfer_direction=SG_DXFER_FROM_DEV and an empty 6-byte cmdp. This may lead to copying up to 1000 kernel     heap pages to the userspace. This has been fixed upstream in     https://github.com/torvalds/linux/commit/a45b599ad808c3c982fdcdc12b0b8611c2f92824 already. The problem has     limited scope, as users don't usually have permissions to access SCSI devices. On the other hand, e.g. the     Nero user manual suggests doing `chmod o+r+w /dev/sg*` to make the devices accessible. NOTE: third parties     dispute the relevance of this report, noting that the requirement for an attacker to have both the     CAP_SYS_ADMIN and CAP_SYS_RAWIO capabilities makes it virtually impossible to exploit. (CVE-2018-1000204)

  - drivers/scsi/libsas/sas_scsi_host.c in the Linux kernel before 4.16 allows local users to cause a denial     of service (ata qc leak) by triggering certain failure conditions.

  - The ext4_iget function in fs/ext4/inode.c in the Linux kernel through 4.15.15 mishandles the case of a     root directory with a zero i_links_count, which allows attackers to cause a denial of service     (ext4_process_freed_data NULL pointer dereference and OOPS) via a crafted ext4 image. (CVE-2018-1092)

  - The ext4_valid_block_bitmap function in fs/ext4/balloc.c in the Linux kernel through 4.15.15 allows     attackers to cause a denial of service (out-of-bounds read and system crash) via a crafted ext4 image     because balloc.c and ialloc.c do not validate bitmap block numbers. (CVE-2018-1093)

  - The cdrom_ioctl_media_changed function in drivers/cdrom/cdrom.c in the Linux kernel before 4.16.6 allows     local attackers to use a incorrect bounds check in the CDROM driver CDROM_MEDIA_CHANGED ioctl to read out     kernel memory. (CVE-2018-10940)

  - In the ea_get function in fs/jfs/xattr.c in the Linux kernel through 4.17.1, a memory corruption bug in     JFS can be triggered by calling setxattr twice with two different extended attribute names on the same     file. This vulnerability can be triggered by an unprivileged user with the ability to create files and     execute programs. A kmalloc call is incorrect, leading to slab-out-of-bounds in jfs_xattr.
    (CVE-2018-12233)

  - An issue was discovered in fs/xfs/libxfs/xfs_attr_leaf.c in the Linux kernel through 4.17.3. An OOPS may     occur for a corrupted xfs image after xfs_da_shrink_inode() is called with a NULL bp. (CVE-2018-13094)

  - The inode_init_owner function in fs/inode.c in the Linux kernel through 3.16 allows local users to create     files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and     is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a     plain file whose group ownership is that group. The intended behavior was that the non-member can trigger     creation of a directory (but not a plain file) whose group ownership is that group. The non-member can     escalate privileges by making the plain file executable and SGID. (CVE-2018-13405)

  - An integer overflow in the uvesafb_setcmap function in drivers/video/fbdev/uvesafb.c in the Linux kernel     before 4.17.4 could result in local attackers being able to crash the kernel or potentially elevate     privileges because kmalloc_array is not used. (CVE-2018-13406)

  - The Linux Kernel versions 4.14, 4.15, and 4.16 has a null pointer dereference which can result in an out     of memory (OOM) killing of large mlocked processes. The issue arises from an oom killed process's final     thread calling exit_mmap(), which calls munlock_vma_pages_all() for mlocked vmas.This can happen     synchronously with the oom reaper's unmap_page_range() since the vma's VM_LOCKED bit is cleared before     munlocking (to determine if any other vmas share the memory and are mlocked). (CVE-2018-1000200)

  - Linux Kernel version 3.18 to 4.16 incorrectly handles an SG_IO ioctl on /dev/sg0 with     dxfer_direction=SG_DXFER_FROM_DEV and an empty 6-byte cmdp.

  - kernel drivers before version 4.17-rc1 are vulnerable to a weakness in the Linux kernel's implementation     of random seed data. Programs, early in the boot sequence, could use the data allocated for the seed     before it was sufficiently generated. (CVE-2018-1108)

  - A flaw was found affecting the Linux kernel before version 4.17. By mmap()ing a FUSE-backed file onto a     process's memory containing command line arguments (or environment strings), an attacker can cause     utilities from psutils or procps (such as ps, w) or any other program which makes a read() call to the     /proc/<pid>/cmdline (or /proc/<pid>/environ) files to block indefinitely (denial of service) or for some     controlled time (as a synchronization primitive for other attacks). (CVE-2018-1120)

  - In the Linux kernel 4.13 through 4.16.11, ext4_read_inline_data() in fs/ext4/inline.c performs a memcpy     with an untrusted length value in certain circumstances involving a crafted filesystem that stores the     system.data extended attribute value in a dedicated inode. (CVE-2018-11412)

  - The sr_do_ioctl function in drivers/scsi/sr_ioctl.c in the Linux kernel through 4.16.12 allows local users     to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact     because sense buffers have different sizes at the CDROM layer and the SCSI layer, as demonstrated by a     CDROMREADMODE2 ioctl call.

(CVE-2018-5814)

  - In driver_override_store and driver_override_show of bus.c, there is a possible double free due to     improper locking. This could lead to local escalation of privilege with System execution privileges     needed. User interaction is not needed for exploitation. Product: Android Versions: Android kernel Android     ID: A-69129004 References: Upstream kernel. (CVE-2018-9415)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Ubuntu 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3752-1 advisory.

  - The Linux Kernel versions 4.14, 4.15, and 4.16 has a null pointer dereference which can result in an out     of memory (OOM) killing of large mlocked processes. The issue arises from an oom killed process's final     thread calling exit_mmap(), which calls munlock_vma_pages_all() for mlocked vmas.This can happen     synchronously with the oom reaper's unmap_page_range() since the vma's VM_LOCKED bit is cleared before     munlocking (to determine if any other vmas share the memory and are mlocked). (CVE-2018-1000200)

  - Linux Kernel version 3.18 to 4.16 incorrectly handles an SG_IO ioctl on /dev/sg0 with     dxfer_direction=SG_DXFER_FROM_DEV and an empty 6-byte cmdp. This may lead to copying up to 1000 kernel     heap pages to the userspace. This has been fixed upstream in     https://github.com/torvalds/linux/commit/a45b599ad808c3c982fdcdc12b0b8611c2f92824 already. The problem has     limited scope, as users don't usually have permissions to access SCSI devices. On the other hand, e.g. the     Nero user manual suggests doing `chmod o+r+w /dev/sg*` to make the devices accessible. NOTE: third parties     dispute the relevance of this report, noting that the requirement for an attacker to have both the     CAP_SYS_ADMIN and CAP_SYS_RAWIO capabilities makes it virtually impossible to exploit. (CVE-2018-1000204)

  - The xfs_bmap_extents_to_btree function in fs/xfs/libxfs/xfs_bmap.c in the Linux kernel through 4.16.3     allows local users to cause a denial of service (xfs_bmapi_write NULL pointer dereference) via a crafted     xfs image. (CVE-2018-10323)

  - Linux kernel is vulnerable to a heap-based buffer overflow in the fs/ext4/xattr.c:ext4_xattr_set_entry()     function. An attacker could exploit this by operating on a mounted crafted ext4 image. (CVE-2018-10840)

  - A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause an out-of-bound access in     ext4_get_group_info function, a denial of service, and a system crash by mounting and operating on a     crafted ext4 filesystem image. (CVE-2018-10881)

  - The ext4_valid_block_bitmap function in fs/ext4/balloc.c in the Linux kernel through 4.15.15 allows     attackers to cause a denial of service (out-of-bounds read and system crash) via a crafted ext4 image     because balloc.c and ialloc.c do not validate bitmap block numbers. (CVE-2018-1093)

  - kernel drivers before version 4.17-rc1 are vulnerable to a weakness in the Linux kernel's implementation     of random seed data. Programs, early in the boot sequence, could use the data allocated for the seed     before it was sufficiently generated. (CVE-2018-1108)

  - A flaw was found affecting the Linux kernel before version 4.17. By mmap()ing a FUSE-backed file onto a     process's memory containing command line arguments (or environment strings), an attacker can cause     utilities from psutils or procps (such as ps, w) or any other program which makes a read() call to the     /proc/<pid>/cmdline (or /proc/<pid>/environ) files to block indefinitely (denial of service) or for some     controlled time (as a synchronization primitive for other attacks). (CVE-2018-1120)

  - In the Linux kernel 4.13 through 4.16.11, ext4_read_inline_data() in fs/ext4/inline.c performs a memcpy     with an untrusted length value in certain circumstances involving a crafted filesystem that stores the     system.data extended attribute value in a dedicated inode. (CVE-2018-11412)

  - The sr_do_ioctl function in drivers/scsi/sr_ioctl.c in the Linux kernel through 4.16.12 allows local users     to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact     because sense buffers have different sizes at the CDROM layer and the SCSI layer, as demonstrated by a     CDROMREADMODE2 ioctl call. (CVE-2018-11506)

  - In net/socket.c in the Linux kernel through 4.17.1, there is a race condition between fchownat and close     in cases where they target the same socket file descriptor, related to the sock_close and sockfs_setattr     functions. fchownat does not increment the file descriptor reference count, which allows close to set the     socket to NULL during fchownat's execution, leading to a NULL pointer dereference and system crash.
    (CVE-2018-12232)

  - In the ea_get function in fs/jfs/xattr.c in the Linux kernel through 4.17.1, a memory corruption bug in     JFS can be triggered by calling setxattr twice with two different extended attribute names on the same     file. This vulnerability can be triggered by an unprivileged user with the ability to create files and     execute programs. A kmalloc call is incorrect, leading to slab-out-of-bounds in jfs_xattr.
    (CVE-2018-12233)

  - In arch/x86/kvm/vmx.c in the Linux kernel before 4.17.2, when nested virtualization is used, local     attackers could cause L1 KVM guests to VMEXIT, potentially allowing privilege escalations and denial of     service attacks due to lack of checking of CPL. (CVE-2018-12904)

  - An issue was discovered in fs/xfs/libxfs/xfs_attr_leaf.c in the Linux kernel through 4.17.3. An OOPS may     occur for a corrupted xfs image after xfs_da_shrink_inode() is called with a NULL bp. (CVE-2018-13094)

  - The inode_init_owner function in fs/inode.c in the Linux kernel through 3.16 allows local users to create     files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and     is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a     plain file whose group ownership is that group. The intended behavior was that the non-member can trigger     creation of a directory (but not a plain file) whose group ownership is that group. The non-member can     escalate privileges by making the plain file executable and SGID. (CVE-2018-13405)

  - An integer overflow in the uvesafb_setcmap function in drivers/video/fbdev/uvesafb.c in the Linux kernel     before 4.17.4 could result in local attackers being able to crash the kernel or potentially elevate     privileges because kmalloc_array is not used. (CVE-2018-13406)

  - In the Linux Kernel before version 4.16.11, 4.14.43, 4.9.102, and 4.4.133, multiple race condition errors     when handling probe, disconnect, and rebind operations can be exploited to trigger a use-after-free     condition or a NULL pointer dereference by sending multiple USB over IP packets. (CVE-2018-5814)

  - In driver_override_store and driver_override_show of bus.c, there is a possible double free due to     improper locking. This could lead to local escalation of privilege with System execution privileges     needed. User interaction is not needed for exploitation. Product: Android Versions: Android kernel Android     ID: A-69129004 References: Upstream kernel. (CVE-2018-9415)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

  - CVE-2018-1068: A flaw was found in the implementation of     32-bit syscall interface for bridging. This allowed a     privileged user to arbitrarily write to a limited range     of kernel memory (bnc#1085107).

  - CVE-2018-1130: A NULL pointer dereference in     dccp_write_xmit() function in net/dccp/output.c allowed     a local user to cause a denial of service by a number of     certain crafted system calls (bnc#1092904).

  - CVE-2018-12233: In the ea_get function in fs/jfs/xattr.c     a memory corruption bug in JFS can be triggered by     calling setxattr twice with two different extended     attribute names on the same file. This vulnerability can     be triggered by an unprivileged user with the ability to     create files and execute programs. A kmalloc call is     incorrect, leading to slab-out-of-bounds in jfs_xattr     (bnc#1097234).

  - CVE-2018-13053: The alarm_timer_nsleep function in     kernel/time/alarmtimer.c had an integer overflow via a     large relative timeout because ktime_add_safe is not     used (bnc#1099924).

  - CVE-2018-13406: An integer overflow in the     uvesafb_setcmap function in     drivers/video/fbdev/uvesafb.c kernel could result in     local attackers being able to crash the kernel or     potentially elevate privileges because kmalloc_array is     not used (bnc#1098016 1100418).

  - CVE-2018-3620: Local attackers on baremetal systems     could use speculative code patterns on hyperthreaded     processors to read data present in the L1 Datacache used     by other hyperthreads on the same CPU core, potentially     leaking sensitive data. (bnc#1087081).

  - CVE-2018-3646: Local attackers in virtualized guest     systems could use speculative code patterns on     hyperthreaded processors to read data present in the L1     Datacache used by other hyperthreads on the same CPU     core, potentially leaking sensitive data, even from     other virtual machines or the host system.
    (bnc#1089343).

  - CVE-2018-5803: An error in the '_sctp_make_chunk()'     function (net/sctp/sm_make_chunk.c) when handling SCTP     packets length could be exploited to cause a kernel     crash (bnc#1083900).

  - CVE-2018-5814: Multiple race condition errors when     handling probe, disconnect, and rebind operations could     be exploited to trigger a use-after-free condition or a     NULL pointer dereference by sending multiple USB over IP     packets (bnc#1096480).

  - CVE-2018-7492: A NULL pointer dereference was found in     the net/rds/rdma.c __rds_rdma_map() function allowing     local attackers to cause a system panic and a     denial-of-service, related to RDS_GET_MR and     RDS_GET_MR_FOR_DEST (bnc#1082962).

The update package also includes non-security fixes. See advisory for details.

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2018-4195 advisory.

  - Systems with microprocessors utilizing speculative execution and address translations may allow     unauthorized disclosure of information residing in the L1 data cache to an attacker with local user access     via a terminal page fault and a side-channel analysis. (CVE-2018-3620)

  - Systems with microprocessors utilizing speculative execution and address translations may allow     unauthorized disclosure of information residing in the L1 data cache to an attacker with local user access     with guest OS privilege via a terminal page fault and a side-channel analysis. (CVE-2018-3646)

  - The Linux kernel, versions 3.9+, is vulnerable to a denial of service attack with low rates of specially     modified packets targeting IP fragment re-assembly. An attacker may cause a denial of service condition by     sending specially crafted IP fragments. Various vulnerabilities in IP fragmentation have been discovered     and fixed over the years. The current vulnerability (CVE-2018-5391) became exploitable in the Linux kernel     with the increase of the IP fragment reassembly queue size. (CVE-2018-5391)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Linux 4.9 has been packaged for Debian 8 as linux-4.9. This provides a supported upgrade path for systems that currently use kernel packages from the 'jessie-backports' suite.

There is no need to upgrade systems using Linux 3.16, as that kernel version will also continue to be supported in the LTS period.

This backport does not include the following binary packages :

hyperv-daemons libcpupower1 libcpupower-dev libusbip-dev linux-compiler-gcc-4.9-x86 linux-cpupower linux-libc-dev usbip

Older versions of most of those are built from other source packages in Debian 8.

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

CVE-2017-5753

Further instances of code that was vulnerable to Spectre variant 1 (bounds-check bypass) have been mitigated.

CVE-2017-18255

It was discovered that the performance events subsystem did not properly validate the value of the kernel.perf_cpu_time_max_percent sysctl. Setting a large value could have an unspecified security impact. However, only a privileged user can set this sysctl.

CVE-2018-1118

The syzbot software found that the vhost driver did not initialise message buffers which would later be read by user processes. A user with access to the /dev/vhost-net device could use this to read sensitive information from the kernel or other users' processes.

CVE-2018-1120

Qualys reported that a user able to mount FUSE filesystems can create a process such that when another process attempting to read its command line will be blocked for an arbitrarily long time. This could be used for denial of service, or to aid in exploiting a race condition in the other program.

CVE-2018-1130

The syzbot software found that the DCCP implementation of sendmsg() does not check the socket state, potentially leading to a NULL pointer dereference. A local user could use this to cause a denial of service (crash). 

CVE-2018-3639

Multiple researchers have discovered that Speculative Store Bypass (SSB), a feature implemented in many processors, could be used to read sensitive information from another context. In particular, code in a software sandbox may be able to read sensitive information from outside the sandbox. This issue is also known as Spectre variant 4.

This update allows the issue to be mitigated on some x86 processors by disabling SSB. This requires an update to the processor's microcode, which is non-free. It may be included in an update to the system BIOS or UEFI firmware, or in a future update to the intel-microcode or amd64-microcode packages.

Disabling SSB can reduce performance significantly, so by default it is only done in tasks that use the seccomp feature. Applications that require this mitigation should request it explicitly through the prctl() system call. Users can control where the mitigation is enabled with the spec_store_bypass_disable kernel parameter.

CVE-2018-5814

Jakub Jirasek reported race conditions in the USB/IP host driver. A malicious client could use this to cause a denial of service (crash or memory corruption), and possibly to execute code, on a USB/IP server.

CVE-2018-10021

A physically present attacker who unplugs a SAS cable can cause a denial of service (memory leak and WARN).

CVE-2018-10087, CVE-2018-10124

zhongjiang found that the wait4() and kill() system call implementations did not check for the invalid pid value of INT_MIN. If a user passed this value, the behaviour of the code was formally undefined and might have had a security impact.

CVE-2018-10853

Andy Lutomirski and Mika Penttil&auml; reported that KVM for x86 processors did not perform a necessary privilege check when emulating certain instructions. This could be used by an unprivileged user in a guest VM to escalate their privileges within the guest.

CVE-2018-10876, CVE-2018-10877, CVE-2018-10878, CVE-2018-10879, CVE-2018-10880, CVE-2018-10881, CVE-2018-10882, CVE-2018-10883

Wen Xu at SSLab, Gatech, reported that crafted ext4 filesystem images could trigger a crash or memory corruption. A local user able to mount arbitrary filesystems, or an attacker providing filesystems to be mounted, could use this for denial of service or possibly for privilege escalation.

CVE-2018-10940

Dan Carpenter reported that the optical disc driver (cdrom) does not correctly validate the parameter to the CDROM_MEDIA_CHANGED ioctl. A user with access to a cdrom device could use this to cause a denial of service (crash).

CVE-2018-11506

Piotr Gabriel Kosinski and Daniel Shapira reported that the SCSI optical disc driver (sr) did not allocate a sufficiently large buffer for sense data. A user with access to a SCSI optical disc device that can produce more than 64 bytes of sense data could use this to cause a denial of service (crash or memory corruption), and possibly for privilege escalation.

CVE-2018-12233

Shankara Pailoor reported that a crafted JFS filesystem image could trigger a denial of service (memory corruption). This could possibly also be used for privilege escalation.

CVE-2018-1000204

The syzbot software found that the SCSI generic driver (sg) would in some circumstances allow reading data from uninitialised buffers, which could include sensitive information from the kernel or other tasks. However, only privileged users with the CAP_SYS_ADMIN or CAP_SYS_RAWIO capability were allowed to do this, so this has little or no security impact.

For Debian 8 'Jessie', these problems have been fixed in version 4.9.110-1~deb8u1. This update additionally fixes Debian bugs #860900, #872907, #892057, #896775, #897590, and #898137; and includes many more bug fixes from stable updates 4.9.89-4.9.110 inclusive.

We recommend that you upgrade your linux-4.9 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The previous update to linux failed to build for the armhf (ARM EABI hard-float) architecture. This update corrects that. For all other architectures, there is no need to upgrade or reboot again. For reference, the relevant part of the original advisory text follows.

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

CVE-2017-5715

Multiple researchers have discovered a vulnerability in various processors supporting speculative execution, enabling an attacker controlling an unprivileged process to read memory from arbitrary addresses, including from the kernel and all other processes running on the system.

This specific attack has been named Spectre variant 2 (branch target injection) and is mitigated for the x86 architecture (amd64 and i386) by using new microcoded features.

This mitigation requires an update to the processor's microcode, which is non-free. For recent Intel processors, this is included in the intel-microcode package from version 3.20180425.1~deb8u1. For other processors, it may be included in an update to the system BIOS or UEFI firmware, or in a later update to the amd64-microcode package.

This vulnerability was already mitigated for the x86 architecture by the 'retpoline' feature.

CVE-2017-5753

Further instances of code that was vulnerable to Spectre variant 1 (bounds-check bypass) have been mitigated.

CVE-2018-1066

Dan Aloni reported to Red Hat that the CIFS client implementation would dereference a NULL pointer if the server sent an invalid response during NTLMSSP setup negotiation. This could be used by a malicious server for denial of service.

The previously applied mitigation for this issue was not appropriate for Linux 3.16 and has been replaced by an alternate fix.

CVE-2018-1093

Wen Xu reported that a crafted ext4 filesystem image could trigger an out-of-bounds read in the ext4_valid_block_bitmap() function. A local user able to mount arbitrary filesystems could use this for denial of service.

CVE-2018-1130

The syzbot software found that the DCCP implementation of sendmsg() does not check the socket state, potentially leading to a NULL pointer dereference. A local user could use this to cause a denial of service (crash). 

CVE-2018-3665

Multiple researchers have discovered that some Intel x86 processors can speculatively read floating-point and vector registers even when access to those registers is disabled. The Linux kernel's 'lazy FPU' feature relies on that access control to avoid saving and restoring those registers for tasks that do not use them, and was enabled by default on x86 processors that do not support the XSAVEOPT instruction.

If 'lazy FPU' is enabled on one of the affected processors, an attacker controlling an unprivileged process may be able to read sensitive information from other users' processes or the kernel. This specifically affects processors based on the 'Nehalem' and 'Westemere' core designs. This issue has been mitigated by disabling 'lazy FPU' by default on all x86 processors that support the FXSAVE and FXRSTOR instructions, which includes all processors known to be affected and most processors that perform speculative execution. It can also be mitigated by adding the kernel parameter: eagerfpu=on

CVE-2018-5814

Jakub Jirasek reported race conditions in the USB/IP host driver. A malicious client could use this to cause a denial of service (crash or memory corruption), and possibly to execute code, on a USB/IP server.

CVE-2018-9422

It was reported that the futex() system call could be used by an unprivileged user for privilege escalation.

CVE-2018-10853

Andy Lutomirski and Mika Penttil&auml; reported that KVM for x86 processors did not perform a necessary privilege check when emulating certain instructions. This could be used by an unprivileged user in a guest VM to escalate their privileges within the guest.

The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.136 to receive various security and bugfixes. The following security bugs were fixed :

  - CVE-2018-5848: In the function wmi_set_ie(), the length     validation code did not handle unsigned integer overflow     properly. As a result, a large value of the 'ie_len'     argument could have caused a buffer overflow     (bnc#1097356).

  - CVE-2017-18249: The add_free_nid function did not     properly track an allocated nid, which allowed local     users to cause a denial of service (race condition) or     possibly have unspecified other impact via concurrent     threads (bnc#1087036).

  - CVE-2018-3665: Prevent disclosure of FPU registers     (including XMM and AVX registers) between processes.
    These registers might contain encryption keys when doing     SSE accelerated AES enc/decryption (bsc#1087086).

  - CVE-2017-18241: Prevent a NULL pointer dereference by     using a noflush_merge option that triggers a NULL value     for a flush_cmd_control data structure (bnc#1086400).

  - CVE-2017-17741: The KVM implementation in the Linux     kernel allowed attackers to obtain potentially sensitive     information from kernel memory, aka a write_mmio     stack-based out-of-bounds read (bnc#1073311).

  - CVE-2018-12233: In the ea_get function in     fs/jfs/xattr.c, a memory corruption bug in JFS can be     triggered by calling setxattr twice with two different     extended attribute names on the same file. This     vulnerability can be triggered by an unprivileged user     with the ability to create files and execute programs. A     kmalloc call is incorrect, leading to slab-out-of-bounds     in jfs_xattr (bnc#1097234).

The update package also includes non-security fixes. See advisory for details.
