drivers/uwb/uwbd.c in the Linux kernel before 4.13.6 allows local users to cause a denial of service (general protection fault and system crash) or possibly have unspecified other impact via a crafted USB device.

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 :

  - An out-of-bounds memory access flaw was found in the     Linux kernel's system call auditing implementation. On     a system with existing audit rules defined, a local,     unprivileged user could use this flaw to leak kernel     memory to user space or, potentially, crash the     system.(CVE-2014-3917i1/4%0

  - The net/netfilter/nfnetlink_cthelper.c function in the     Linux kernel through 4.14.4 does not require the     CAP_NET_ADMIN capability for new, get, and del     operations. This allows local users to bypass intended     access restrictions because the nfnl_cthelper_list data     structure is shared across all net     namespaces.(CVE-2017-17448i1/4%0

  - A race condition flaw was found between the chown and     execve system calls. When changing the owner of a     setuid user binary to root, the race condition could     momentarily make the binary setuid root. A local,     unprivileged user could potentially use this flaw to     escalate their privileges on the     system.(CVE-2015-3339i1/4%0

  - Keberos 5 tickets being decoded when using the RXRPC     keys incorrectly assumes the size of a field. This     could lead to the size-remaining variable wrapping and     the data pointer going over the end of the buffer. This     could possibly lead to memory corruption and possible     privilege escalation.(CVE-2017-7482i1/4%0

  - The nfs_can_extend_write function in fs/nfs/write.c in     the Linux kernel before 3.13.3 relies on a write     delegation to extend a write operation without a     certain up-to-date verification, which allows local     users to obtain sensitive information from kernel     memory in opportunistic circumstances by writing to a     file in an NFS filesystem and then reading the same     file.(CVE-2014-2038i1/4%0

  - KVM in the Linux kernel before 4.8.12, when I/O APIC is     enabled, does not properly restrict the VCPU index,     which allows guest OS users to gain host OS privileges     or cause a denial of service (out-of-bounds array     access and host OS crash) via a crafted interrupt     request, related to arch/x86/kvm/ioapic.c and     arch/x86/kvm/ioapic.h.(CVE-2016-9777i1/4%0

  - The instruction decoder in arch/x86/kvm/emulate.c in     the KVM subsystem in the Linux kernel before 3.18-rc2     lacks intended decoder-table flags for certain     RIP-relative instructions, which allows guest OS users     to cause a denial of service (NULL pointer dereference     and host OS crash) via a crafted     application.(CVE-2014-8480i1/4%0

  - arch/x86/kernel/entry_32.S in the Linux kernel through     3.15.1 on 32-bit x86 platforms, when syscall auditing     is enabled and the sep CPU feature flag is set, allows     local users to cause a denial of service (OOPS and     system crash) via an invalid syscall number, as     demonstrated by number 1000.(CVE-2014-4508i1/4%0

  - The overlayfs implementation in the Linux kernel     through 4.5.2 does not properly restrict the mount     namespace, which allows local users to gain privileges     by mounting an overlayfs filesystem on top of a FUSE     filesystem, and then executing a crafted setuid     program.(CVE-2016-1576i1/4%0

  - A use-after-free vulnerability was found when issuing     an ioctl to a sound device. This could allow a user to     exploit a race condition and create memory corruption     or possibly privilege escalation.(CVE-2017-15265i1/4%0

  - The drivers/uwb/uwbd.c in the Linux kernel, before     4.13.6, allows local users to cause a denial of service     (general protection fault and system crash) or possibly     have unspecified other impact via a crafted USB     device.(CVE-2017-16526i1/4%0

  - The Linux kernel was found vulnerable to a NULL pointer     dereference in the     drivers/net/phy/mdio-bcm-unimac.c:unimac_mdio_probe()     function caused by an unchecked return value from the     platform_get_resource() function. A successful flaw     exploitation can cause a system panic and a denial of     service. This flaw is believed not to be an attacker     triggerable as bad return value can be caused by     hardware misconfiguration.(CVE-2018-8043i1/4%0

  - A flaw was found in the Linux kernel SCSI subsystem,     which allowed a local user to gain privileges or cause     a denial of service (memory corruption and system     crash) by issuing an SG_IO ioctl call while a device     was being detached.(CVE-2015-8962i1/4%0

  - The xc2028_set_config function in     drivers/media/tuners/tuner-xc2028.c in the Linux kernel     before 4.6 allows local users to gain privileges or     cause a denial of service (use-after-free) via vectors     involving omission of the firmware name from a certain     data structure. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2016-7913i1/4%0

  - drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver     in the Linux kernel through 4.0.5 does not ensure that     certain length values are sufficiently large, which     allows remote attackers to cause a denial of service     (system crash or large loop) or possibly execute     arbitrary code via a crafted packet, related to the (1)     oz_usb_rx and (2) oz_usb_handle_ep_data     functions.(CVE-2015-4002i1/4%0

  - Race condition in the environ_read() function in     'fs/proc/base.c' in the Linux kernel before 4.5.4     allows local users to obtain sensitive information from     kernel memory by reading a '/proc/*/environ' file     during a process-setup time interval in which     environment-variable copying is     incomplete.(CVE-2016-7916i1/4%0

  - Integer signedness error in the oz_hcd_get_desc_cnf     function in drivers/staging/ozwpan/ozhcd.c in the     OZWPAN driver in the Linux kernel through 4.0.5 allows     remote attackers to cause a denial of service (system     crash) or possibly execute arbitrary code via a crafted     packet.(CVE-2015-4001i1/4%0

  - A vulnerability was found in the Linux kernel when     peeling off an association to the socket in another     network namespace. All transports in this association     are not to be rehashed and keep using the old key in     hashtable, thus removing transports from hashtable when     closing the socket, all transports are being freed.
    Later on a use-after-free issue could be caused when     looking up an association and dereferencing the     transports.(CVE-2017-15115i1/4%0

  - The evm_verify_hmac function in     security/integrity/evm/evm_main.c in the Linux kernel     before 4.5 does not properly copy data, which makes it     easier for local users to forge MAC values via a timing     side-channel attack.(CVE-2016-2085i1/4%0

  - A flaw was discovered in processing setsockopt for 32     bit processes on 64 bit systems. This flaw will allow     attackers to alter arbitrary kernel memory when     unloading a kernel module. This action is usually     restricted to root-privileged users but can also be     leveraged if the kernel is compiled with CONFIG_USER_NS     and CONFIG_NET_NS and the user is granted elevated     privileges.(CVE-2016-4997i1/4%0

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

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

  - It was found that in the Linux kernel through     v4.14-rc5, bio_map_user_iov() and bio_unmap_user() in     'block/bio.c' do unbalanced pages refcounting if IO     vector has small consecutive buffers belonging to the     same page. bio_add_pc_page() merges them into one, but     the page reference is never dropped, causing a memory     leak and possible system lockup due to out-of-memory     condition.(CVE-2017-12190)

  - A vulnerability was found in the Key Management sub     component of the Linux kernel, where when trying to     issue a KEYTCL_READ on a negative key would lead to a     NULL pointer dereference. A local attacker could use     this flaw to crash the kernel.(CVE-2017-12192)

  - A flaw was found in the Linux kernel's implementation     of associative arrays introduced in 3.13. This     functionality was backported to the 3.10 kernels in Red     Hat Enterprise Linux 7. The flaw involved a null     pointer dereference in assoc_array_apply_edit() due to     incorrect node-splitting in assoc_array implementation.
    This affects the keyring key type and thus key addition     and link creation operations may cause the kernel to     panic.(CVE-2017-12193)

  - A divide-by-zero vulnerability was found in the
    __tcp_select_window function in the Linux kernel. This     can result in a kernel panic causing a local denial of     service.(CVE-2017-14106)

  - The move_pages system call in mm/migrate.c in the Linux     kernel doesn't check the effective uid of the target     process. This enables a local attacker to learn the     memory layout of a setuid executable allowing     mitigation of ASLR.(CVE-2017-14140)

  - The iscsi_if_rx() function in     'drivers/scsi/scsi_transport_iscsi.c' in the Linux     kernel from v2.6.24-rc1 through 4.13.2 allows local     users to cause a denial of service (a system panic) by     making a number of certain syscalls by leveraging     incorrect length validation in the kernel     code.(CVE-2017-14489)

  - The sg_ioctl() function in 'drivers/scsi/sg.c' in the     Linux kernel, from version 4.12-rc1 to 4.14-rc2, allows     local users to obtain sensitive information from     uninitialized kernel heap-memory locations via an     SG_GET_REQUEST_TABLE ioctl call for     '/dev/sg0'.(CVE-2017-14991)

  - The tower_probe function in     drivers/usb/misc/legousbtower.c in the Linux kernel     before 4.8.1 allows local users (who are physically     proximate for inserting a crafted USB device) to gain     privileges by leveraging a write-what-where condition     that occurs after a race condition and a NULL pointer     dereference.(CVE-2017-15102)

  - A vulnerability was found in the Linux kernel when     peeling off an association to the socket in another     network namespace. All transports in this association     are not to be rehashed and keep using the old key in     hashtable, thus removing transports from hashtable when     closing the socket, all transports are being freed.
    Later on a use-after-free issue could be caused when     looking up an association and dereferencing the     transports.(CVE-2017-15115)

  - A use-after-free vulnerability was found in a network     namespaces code affecting the Linux kernel since     v4.0-rc1 through v4.15-rc5. The function     get_net_ns_by_id() does not check for the net::count     value after it has found a peer network in netns_ids     idr which could lead to double free and memory     corruption. This vulnerability could allow an     unprivileged local user to induce kernel memory     corruption on the system, leading to a crash. Due to     the nature of the flaw, privilege escalation cannot be     fully ruled out, although it is thought to be     unlikely.(CVE-2017-15129)

  - A use-after-free vulnerability was found when issuing     an ioctl to a sound device. This could allow a user to     exploit a race condition and create memory corruption     or possibly privilege escalation.(CVE-2017-15265)

  - A flaw was found in the implementation of associative     arrays where the add_key systemcall and KEYCTL_UPDATE     operations allowed for a NULL payload with a nonzero     length. When accessing the payload within this length     parameters value, an unprivileged user could trivially     cause a NULL pointer dereference (kernel     oops).(CVE-2017-15274)

  - A vulnerability was found in the key management     subsystem of the Linux kernel. An update on an     uninstantiated key could cause a kernel panic, leading     to denial of service (DoS).(CVE-2017-15299)

  - 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)

  - The saa7164_bus_get function in drivers/media/pci/saa7164/saa7164-bus.c in the Linux kernel through 4.11.5     allows local users to cause a denial of service (out-of-bounds array access) or possibly have unspecified     other impact by changing a certain sequence-number value, aka a double fetch vulnerability.
    (CVE-2017-8831)

  - The snd_msnd_interrupt function in sound/isa/msnd/msnd_pinnacle.c in the Linux kernel through 4.11.7     allows local users to cause a denial of service (over-boundary access) or possibly have unspecified other     impact by changing the value of a message queue head pointer between two kernel reads of that value, aka a     double fetch vulnerability. (CVE-2017-9984)

  - The snd_msndmidi_input_read function in sound/isa/msnd/msnd_midi.c in the Linux kernel through 4.11.7     allows local users to cause a denial of service (over-boundary access) or possibly have unspecified other     impact by changing the value of a message queue head pointer between two kernel reads of that value, aka a     double fetch vulnerability. (CVE-2017-9985)

  - 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. NOTE: a third party disputes the     relevance of this report because the failure can only occur for physically proximate attackers who unplug     SAS Host Bus Adapter cables (CVE-2018-10021)

  - The kernel_wait4 function in kernel/exit.c in the Linux kernel before 4.13, when an unspecified     architecture and compiler is used, might allow local users to cause a denial of service by triggering an     attempted use of the -INT_MIN value. (CVE-2018-10087)

  - The kill_something_info function in kernel/signal.c in the Linux kernel before 4.13, when an unspecified     architecture and compiler is used, might allow local users to cause a denial of service via an INT_MIN     argument. (CVE-2018-10124)

  - 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)

  - The do_get_mempolicy function in mm/mempolicy.c in the Linux kernel before 4.12.9 allows local users to     cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted system     calls. (CVE-2018-10675)

  - Linux kernel ext4 filesystem is vulnerable to an out-of-bound access in the ext4_ext_drop_refs() function     when operating on a crafted ext4 filesystem image. (CVE-2018-10877)

  - 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_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 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 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-2017-16643)

  - In the Linux kernel through 3.2, the rds_message_alloc_sgs() function does not validate a value that is     used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the     rds_rdma_extra_size function in net/rds/rdma.c). (CVE-2018-5332)

  - 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-2017-16537)

  - The KEYS subsystem in the Linux kernel through 4.13.7 mishandles use of add_key for a key that already     exists but is uninstantiated, which allows local users to cause a denial of service (NULL pointer     dereference and system crash) or possibly have unspecified other impact via a crafted system call.

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

CVE-2017-0861

Robb Glasser reported a potential use-after-free in the ALSA (sound) PCM core. We believe this was not possible in practice.

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 the 'retpoline' compiler feature which allows indirect branches to be isolated from speculative execution.

CVE-2017-13166

A bug in the 32-bit compatibility layer of the v4l2 ioctl handling code has been found. Memory protections ensuring user-provided buffers always point to userland memory were disabled, allowing destination addresses to be in kernel space. On a 64-bit kernel (amd64 flavour) a local user with access to a suitable video device can exploit this to overwrite kernel memory, leading to privilege escalation.

CVE-2017-16526

Andrey Konovalov reported that the UWB subsystem may dereference an invalid pointer in an error case. A local user might be able to use this for denial of service.

CVE-2017-16911

Secunia Research reported that the USB/IP vhci_hcd driver exposed kernel heap addresses to local users. This information could aid the exploitation of other vulnerabilities.

CVE-2017-16912

Secunia Research reported that the USB/IP stub driver failed to perform a range check on a received packet header field, leading to an out-of-bounds read. A remote user able to connect to the USB/IP server could use this for denial of service.

CVE-2017-16913

Secunia Research reported that the USB/IP stub driver failed to perform a range check on a received packet header field, leading to excessive memory allocation. A remote user able to connect to the USB/IP server could use this for denial of service.

CVE-2017-16914

Secunia Research reported that the USB/IP stub driver failed to check for an invalid combination of fields in a recieved packet, leading to a NULL pointer dereference. A remote user able to connect to the USB/IP server could use this for denial of service.

CVE-2017-18017

Denys Fedoryshchenko reported that the netfilter xt_TCPMSS module failed to validate TCP header lengths, potentially leading to a use-after-free. If this module is loaded, it could be used by a remote attacker for denial of service or possibly for code execution.

CVE-2017-18203

Hou Tao reported that there was a race condition in creation and deletion of device-mapper (DM) devices. A local user could potentially use this for denial of service.

CVE-2017-18216

Alex Chen reported that the OCFS2 filesystem failed to hold a necessary lock during nodemanager sysfs file operations, potentially leading to a NULL pointer dereference. A local user could use this for denial of service.

CVE-2018-1068

The syzkaller tool found that the 32-bit compatibility layer of ebtables did not sufficiently validate offset values. On a 64-bit kernel (amd64 flavour), a local user with the CAP_NET_ADMIN capability could use this to overwrite kernel memory, possibly leading to privilege escalation.

CVE-2018-1092

Wen Xu reported that a crafted ext4 filesystem image would trigger a null dereference when mounted. A local user able to mount arbitrary filesystems could use this for denial of service.

CVE-2018-5332

Mohamed Ghannam reported that the RDS protocol did not sufficiently validate RDMA requests, leading to an out-of-bounds write. A local attacker on a system with the rds module loaded could use this for denial of service or possibly for privilege escalation.

CVE-2018-5333

Mohamed Ghannam reported that the RDS protocol did not properly handle an error case, leading to a NULL pointer dereference. A local attacker on a system with the rds module loaded could possibly use this for denial of service.

CVE-2018-5750

Wang Qize reported that the ACPI sbshc driver logged a kernel heap address. This information could aid the exploitation of other vulnerabilities.

Additionally, some mitigations for CVE-2017-5753 are included in this release :

CVE-2017-5753

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 1 (bounds-check bypass) and is mitigated by identifying vulnerable code sections (array bounds checking followed by array access) and replacing the array access with the speculation-safe array_index_nospec() function.

More use sites will be added over time.

For Debian 7 'Wheezy', these problems have been fixed in version 3.2.101-1. This version also includes bug fixes from upstream versions up to and including 3.2.101. It also fixes a regression in the procfs hidepid option in the previous version (Debian bug #887106).

We recommend that you upgrade your linux 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 remote Oracle Linux 6 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2018-4088 advisory. Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

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

  - CVE-2015-9016     Ming Lei reported a race condition in the multiqueue     block layer (blk-mq). On a system with a driver using     blk-mq (mtip32xx, null_blk, or virtio_blk), a local user     might be able to use this for denial of service or     possibly for privilege escalation.

  - CVE-2017-0861     Robb Glasser reported a potential use-after-free in the     ALSA (sound) PCM core. We believe this was not possible     in practice.

  - 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 the 'retpoline' compiler feature which allows   indirect branches to be isolated from speculative execution.

  - CVE-2017-5753     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 1 (bounds-check   bypass) and is mitigated by identifying vulnerable code sections   (array bounds checking followed by array access) and replacing the   array access with the speculation-safe array_index_nospec()   function.

  More use sites will be added over time.

  - CVE-2017-13166     A bug in the 32-bit compatibility layer of the v4l2     ioctl handling code has been found.
