The usb_get_bos_descriptor function in drivers/usb/core/config.c in the Linux kernel before 4.13.10 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.

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 :

  - A memory corruption flaw was found in the way the USB     ConnectTech WhiteHEAT serial driver processed     completion commands sent via USB Request Blocks     buffers. An attacker with physical access to the system     could use this flaw to crash the system or,     potentially, escalate their privileges on the     system.(CVE-2014-3185i1/4%0

  - Use-after-free vulnerability in the msm_set_crop     function in drivers/media/video/msm/msm_camera.c in the     MSM-Camera driver for the Linux kernel 3.x, as used in     Qualcomm Innovation Center (QuIC) Android contributions     for MSM devices and other products, allows attackers to     gain privileges or cause a denial of service (memory     corruption) via an application that makes a crafted     ioctl call.(CVE-2015-0568i1/4%0

  - The vivid_fb_ioctl function in     drivers/media/platform/vivid/vivid-osd.c in the Linux     kernel through 4.3.3 does not initialize a certain     structure member, which allows local users to obtain     sensitive information from kernel memory via a crafted     application.(CVE-2015-7884i1/4%0

  - The usb_get_bos_descriptor function in     drivers/usb/core/config.c in the Linux kernel can allow     a 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-2017-16535i1/4%0

  - The ACPI parsing functionality in the Linux kernel does     not flush the node and node_ext caches which causes a     kernel stack dump. This allows local users to obtain     sensitive information from kernel memory and use this     information to bypass the KASLR protection mechanism by     creating and applying crafted ACPI     table.(CVE-2017-13694i1/4%0

  - The is_ashmem_file function in     drivers/staging/android/ashmem.c in a certain Qualcomm     Innovation Center (QuIC) Android patch for the Linux     kernel 3.x mishandles pointer validation within the     KGSL Linux Graphics Module, which allows attackers to     bypass intended access restrictions by using the     /ashmem string as the dentry name.(CVE-2016-5340i1/4%0

  - It was found that the Linux kernel did not properly     account file descriptors passed over the unix socket     against the process limit. A local user could use this     flaw to exhaust all available memory on the     system.(CVE-2013-4312i1/4%0

  - Kernel memory corruption due to a buffer overflow was     found in brcmf_cfg80211_mgmt_tx() function in Linux     kernels from v3.9-rc1 to v4.13-rc1. The vulnerability     can be triggered by sending a crafted NL80211_CMD_FRAME     packet via netlink. This flaw is unlikely to be     triggered remotely as certain userspace code is needed     for this. An unprivileged local user could use this     flaw 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 unlikely.(CVE-2017-7541i1/4%0

  - A flaw in the netback module allowed frontends to     control mapping of requests to request queues. An     attacker can change this mapping by requesting invalid     mapping requests allowing the (usually privileged)     backend to access out-of-bounds memory access for     reading and writing.(CVE-2018-15471i1/4%0

  - A buffer overflow vulnerability due to a lack of input     filtering of incoming fragmented datagrams was found in     the IP-over-1394 driver firewire-net in a fragment     handling code in the Linux kernel. The vulnerability     exists since firewire supported IPv4, i.e. since     version 2.6.31 (year 2009) till version v4.9-rc4. A     maliciously formed fragment with a respectively large     datagram offset would cause a memcpy() past the     datagram buffer, which would cause a system panic or     possible arbitrary code execution.The flaw requires     firewire-net module to be loaded and is remotely     exploitable from connected firewire devices, but not     over a local network.(CVE-2016-8633i1/4%0

  - It was found that the Linux kernel can hit a BUG_ON()     statement in the __xfs_get_blocks() in the     fs/xfs/xfs_aops.c because of a race condition between     direct and memory-mapped I/O associated with a hole in     a file that is handled with BUG_ON() instead of an I/O     failure. This allows a local unprivileged attacker to     cause a system crash and a denial of     service.(CVE-2016-10741i1/4%0

  - A vulnerability was found in the Linux kernel. The     pointer to the netlink socket attribute is not checked,     which could cause a null pointer dereference when     parsing the nested attributes in function     tipc_nl_publ_dump(). This allows local users to cause a     DoS.(CVE-2016-4951i1/4%0

  - It was reported that with Linux kernel, earlier than     version v4.10-rc8, an application may trigger a BUG_ON     in sctp_wait_for_sndbuf if the socket tx buffer is     full, a thread is waiting on it to queue more data, and     meanwhile another thread peels off the association     being used by the first thread.(CVE-2017-5986i1/4%0

  - The kvm_vm_ioctl_check_extension function in     arch/powerpc/kvm/powerpc.c in the Linux kernel before     4.13.11 allows local users to cause a denial of service     (NULL pointer dereference and system crash) via a     KVM_CHECK_EXTENSION KVM_CAP_PPC_HTM ioctl call to     /dev/kvm.(CVE-2017-15306i1/4%0

  - A flaw was found in the way the Linux kernel's 32-bit     emulation implementation handled forking or closing of     a task with an 'int80' entry. A local user could     potentially use this flaw to escalate their privileges     on the system.(CVE-2015-2830i1/4%0

  - A flaw was found in the way the Linux kernel's SCTP     implementation validated INIT chunks when performing     Address Configuration Change (ASCONF). A remote     attacker could use this flaw to crash the system by     sending a specially crafted SCTP packet to trigger a     NULL pointer dereference on the     system.(CVE-2014-7841i1/4%0

  - A race condition issue leading to a use-after-free flaw     was found in the way the raw packet sockets are     implemented in the Linux kernel networking subsystem     handling synchronization. A local user able to open a     raw packet socket (requires the CAP_NET_RAW capability)     can use this issue to crash the     system.(CVE-2017-1000111)

  - A flaw was found in the way the Linux kernel performed     forking inside of a transaction. A local, unprivileged     user on a PowerPC system that supports transactional     memory could use this flaw to crash the     system.(CVE-2014-2673i1/4%0

  - The hashbin_delete function in net/irda/irqueue.c in     the Linux kernel improperly manages lock dropping,     which allows local users to cause a denial of service     (deadlock) via crafted operations on IrDA     devices.(CVE-2017-6348i1/4%0

  - An out-of-bounds flaw was found in the kernel, where     the length of the sockaddr parameter was not checked in     the pptp_bind() and pptp_connect() functions. As a     result, more kernel memory was copied out than     required, leaking information from the kernel stack     (including kernel addresses). A local system user could     exploit this flaw to bypass kernel ASLR or leak other     information.(CVE-2015-8569i1/4%0

This compromises the     validity of the keyring for those who rely on     it.(CVE-2017-17807)

  - A flaw was found in the Linux kernel's implementation     of i8042 serial ports. An attacker could cause a kernel     panic if they are able to add and remove devices as the     module is loaded.(CVE-2017-18079)

  - The Linux kernel, before version 4.14.3, is vulnerable     to a denial of service in     drivers/md/dm.c:dm_get_from_kobject() which can be     caused by local users leveraging a race condition with
    __dm_destroy() during creation and removal of DM     devices. Only privileged local users (with     CAP_SYS_ADMIN capability) can directly perform the     ioctl operations for dm device creation and removal and     this would typically be outside the direct control of     the unprivileged attacker.(CVE-2017-18203)

  - The madvise_willneed function in the Linux kernel     allows local users to cause a denial of service     (infinite loop) by triggering use of MADVISE_WILLNEED     for a DAX mapping.(CVE-2017-18208)

  - 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)

  - 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)

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

The remote Oracle Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2018-4109 advisory.

  - The usb_destroy_configuration function in drivers/usb/core/config.c in the USB core subsystem in the Linux     kernel through 4.14.5 does not consider the maximum number of configurations and interfaces before     attempting to release resources, which allows local users to cause a denial of service (out-of-bounds     write access) or possibly have unspecified other impact via a crafted USB device. (CVE-2017-17558)

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

  - The get_endpoints function in drivers/usb/misc/usbtest.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-2017-16532)

  - A flaw was found in the Linux 4.x kernel's implementation of 32-bit syscall interface for bridging. This     allowed a privileged user to arbitrarily write to a limited range of kernel memory. (CVE-2018-1068)

  - 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.

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

The SUSE Linux Enterprise 11 SP3 LTSS kernel was updated to receive various security and bugfixes. This update adds mitigations for various side channel attacks against modern CPUs that could disclose content of otherwise unreadable memory (bnc#1068032).

  - CVE-2017-5753: Local attackers on systems with modern     CPUs featuring deep instruction pipelining could use     attacker controllable speculative execution over code     patterns in the Linux Kernel to leak content from     otherwise not readable memory in the same address space,     allowing retrieval of passwords, cryptographic keys and     other secrets. This problem is mitigated by adding     speculative fencing on affected code paths throughout     the Linux kernel.

  - CVE-2017-5715: Local attackers on systems with modern     CPUs featuring branch prediction could use mispredicted     branches to speculatively execute code patterns that in     turn could be made to leak other non-readable content in     the same address space, an attack similar to     CVE-2017-5753. This problem is mitigated by disabling     predictive branches, depending on CPU architecture     either by firmware updates and/or fixes in the     user-kernel privilege boundaries.

  - CVE-2017-5754: Local attackers on systems with modern     CPUs featuring deep instruction pipelining could use     code patterns in userspace to speculative executive code     that would read otherwise read protected memory, an     attack similar to CVE-2017-5753. This problem is     mitigated by unmapping the Linux Kernel from the user     address space during user code execution, following a     approach called 'KAISER'. The terms used here are     'KAISER' / 'Kernel Address Isolation' and 'PTI' / 'Page     Table Isolation'. This feature is disabled on unaffected     architectures. This feature can be enabled / disabled by     the 'pti=[on|off|auto]' or 'nopti' commandline options.
    The following security bugs were fixed :

The SUSE Linux Enterprise 12 kernel was updated to 3.12.61 to receive various security and bugfixes. The following security bugs were fixed :

  - CVE-2017-16939: The XFRM dump policy implementation in     net/xfrm/xfrm_user.c in the Linux kernel allowed local     users to gain privileges or cause a denial of service     (use-after-free) via a crafted SO_RCVBUF setsockopt     system call in conjunction with XFRM_MSG_GETPOLICY     Netlink messages (bnc#1069702 1069708).

  - CVE-2017-1000405: The Linux Kernel had a problematic use     of pmd_mkdirty() in the touch_pmd() function inside the     THP implementation. touch_pmd() could be reached by     get_user_pages(). In such case, the pmd would become     dirty. This scenario breaks the new     can_follow_write_pmd()'s logic - pmd could become dirty     without going through a COW cycle. This bug was not as     severe as the original 'Dirty cow' because an ext4 file     (or any other regular file) could not be mapped using     THP. Nevertheless, it did allow us to overwrite     read-only huge pages. For example, the zero huge page     and sealed shmem files could be overwritten (since their     mapping could be populated using THP).

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

CVE-2016-10208

Sergej Schumilo and Ralf Spenneberg discovered that a crafted ext4 filesystem could trigger memory corruption when it is mounted. A user that can provide a device or filesystem image to be mounted could use this for denial of service (crash or data corruption) or possibly for privilege escalation.

CVE-2017-8824

Mohamed Ghannam discovered that the DCCP implementation did not correctly manage resources when a socket is disconnected and reconnected, potentially leading to a use-after-free. A local user could use this for denial of service (crash or data corruption) or possibly for privilege escalation. On systems that do not already have the dccp module loaded, this can be mitigated by disabling it: echo >> /etc/modprobe.d/disable-dccp.conf install dccp false

CVE-2017-8831

Pengfei Wang discovered that the saa7164 video capture driver re-reads data from a PCI device after validating it. A physically present user able to attach a specially designed PCI device could use this for privilege escalation.

CVE-2017-12190

Vitaly Mayatskikh discovered that the block layer did not correctly count page references for raw I/O from user-space. This can be exploited by a guest VM with access to a host SCSI device for denial of service (memory exhaustion) or potentially for privilege escalation.

CVE-2017-13080

A vulnerability was found in the WPA2 protocol that could lead to reinstallation of the same Group Temporal Key (GTK), which substantially reduces the security of wifi encryption. This is one of the issues collectively known as 'KRACK'.

Updates to GTKs are usually handled by the wpa package, where this issue was already fixed (DLA-1150-1). However, some wifi devices can remain active and update GTKs autonomously while the system is suspended. The kernel must also check for and ignore key reinstallation.

CVE-2017-14051

'shqking' reported that the qla2xxx SCSI host driver did not correctly validate I/O to the 'optrom' sysfs attribute of the devices it creates. This is unlikely to have any security impact.

CVE-2017-15115

Vladis Dronov reported that the SCTP implementation did not correctly handle 'peel-off' of an association to another net namespace. This leads to a use-after-free, which a local user can exploit for denial of service (crash or data corruption) or possibly for privilege escalation. On systems that do not already have the sctp module loaded, this can be mitigated by disabling it: echo >> /etc/modprobe.d/disable-sctp.conf install sctp false

CVE-2017-15265

Michael23 Yu reported a race condition in the ALSA sequencer subsystem involving creation and deletion of ports, which could lead to a use-after-free. A local user with access to an ALSA sequencer device can use this for denial of service (crash or data loss) or possibly for privilege escalation.

CVE-2017-15299

A local user can use this for denial of service (crash).

CVE-2017-15649

'nixioaming' reported a race condition in the packet socket (AF_PACKET) implementation involving rebinding to a fanout group, which could lead to a use-after-free. A local user with the CAP_NET_RAW capability can use this for denial of service (crash or data corruption) or possibly for privilege escalation.

CVE-2017-15868

Al Viro found that the Bluebooth Network Encapsulation Protocol (BNEP) implementation did not validate the type of the second socket passed to the BNEPCONNADD ioctl(), which could lead to memory corruption. A local user with the CAP_NET_ADMIN capability can use this for denial of service (crash or data corruption) or possibly for privilege escalation.

CVE-2017-16525

Andrey Konovalov reported that the USB serial console implementation did not correctly handle disconnection of unusual serial devices, leading to a use-after-free. A similar issue was found in the case where setup of a serial console fails. A physically present user with a specially designed USB device can use this to cause a denial of service (crash or data corruption) or possibly for privilege escalation.

CVE-2017-16527

Andrey Konovalov reported that the USB sound mixer driver did not correctly cancel I/O in case it failed to probe a device, which could lead to a use-after-free. A physically present user with a specially designed USB device can use this to cause a denial of service (crash or data corruption) or possibly for privilege escalation.

CVE-2017-16529
