The remote Oracle Linux host is missing a security update for the Unbreakable Enterprise kernel package(s).

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 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-2017-17975     Tuba Yavuz reported a use-after-free flaw in the     USBTV007 audio-video grabber driver. A local user could     use this for denial of service by triggering failure of     audio registration.

  - CVE-2017-18193     Yunlei He reported that the f2fs implementation does not     properly handle extent trees, allowing a local user to     cause a denial of service via an application with     multiple threads.

  - 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-2017-18218     Jun He reported a use-after-free flaw in the Hisilicon     HNS ethernet driver. A local user could use this for     denial of service.

  - CVE-2017-18222     It was reported that the Hisilicon Network Subsystem     (HNS) driver implementation does not properly handle     ethtool private flags. A local user could use this for     denial of service or possibly have other impact.

  - CVE-2017-18224     Alex Chen reported that the OCFS2 filesystem omits the     use of a semaphore and consequently has a race condition     for access to the extent tree during read operations in     DIRECT mode. A local user could use this for denial of     service.

  - CVE-2017-18241     Yunlei He reported that the f2fs implementation does not     properly initialise its state if the 'noflush_merge'     mount option is used. A local user with access to a     filesystem mounted with this option could use this to     cause a denial of service.

  - CVE-2017-18257     It was reported that the f2fs implementation is prone to     an infinite loop caused by an integer overflow in the
    __get_data_block() function. A local user can use this     for denial of service via crafted use of the open and     fallocate system calls with an FS_IOC_FIEMAP ioctl.

  - CVE-2018-1065     The syzkaller tool found a NULL pointer dereference flaw     in the netfilter subsystem when handling certain     malformed iptables rulesets. A local user with the     CAP_NET_RAW or CAP_NET_ADMIN capability (in any user     namespace) could use this to cause a denial of service.
    Debian disables unprivileged user namespaces by default.

  - 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.

  - 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, a local user with the     CAP_NET_ADMIN capability (in any user namespace) could     use this to overwrite kernel memory, possibly leading to     privilege escalation. Debian disables unprivileged user     namespaces by default.

  - 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-2018-1093     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-2018-1108     Jann Horn reported that crng_ready() does not properly     handle the crng_init variable states and the RNG could     be treated as cryptographically safe too early after     system boot.

  - CVE-2018-5803     Alexey Kodanev reported that the SCTP protocol did not     range-check the length of chunks to be created. A local     or remote user could use this to cause a denial of     service.

  - CVE-2018-7480     Hou Tao discovered a double-free flaw in the     blkcg_init_queue() function in block/blk-cgroup.c. A     local user could use this to cause a denial of service     or have other impact.

  - CVE-2018-7566     Fan LongFei reported a race condition in the ALSA     (sound) sequencer core, between write and ioctl     operations. This could lead to an out-of-bounds access     or use-after-free. A local user with access to a     sequencer device could use this for denial of service or     possibly for privilege escalation.

  - CVE-2018-7740     Nic Losby reported that the hugetlbfs filesystem's mmap     operation did not properly range-check the file offset.
    A local user with access to files on a hugetlbfs     filesystem could use this to cause a denial of service.

  - CVE-2018-7757     Jason Yan reported a memory leak in the SAS     (Serial-Attached SCSI) subsystem. A local user on a     system with SAS devices could use this to cause a denial     of service.

  - CVE-2018-7995     Seunghun Han reported a race condition in the x86 MCE     (Machine Check Exception) driver. This is unlikely to     have any security impact.

  - CVE-2018-8087     A memory leak flaw was found in the hwsim_new_radio_nl()     function in the simulated radio testing tool driver for     mac80211, allowing a local user to cause a denial of     service.

  - CVE-2018-8781     Eyal Itkin reported that the udl (DisplayLink) driver's     mmap operation did not properly range-check the file     offset. A local user with access to a udl framebuffer     device could exploit this to overwrite kernel memory,     leading to privilege escalation.

  - CVE-2018-8822     Dr Silvio Cesare of InfoSect reported that the ncpfs     client implementation did not validate reply lengths     from the server. An ncpfs server could use this to cause     a denial of service or remote code execution in the     client.

  - CVE-2018-10323     Wen Xu reported a NULL pointer dereference flaw in the     xfs_bmapi_write() function triggered when mounting and     operating a crafted xfs filesystem image. A local user     able to mount arbitrary filesystems could use this for     denial of service.

  - CVE-2018-1000199     Andy Lutomirski discovered that the ptrace subsystem did     not sufficiently validate hardware breakpoint settings.
    Local users can use this to cause a denial of service,     or possibly for privilege escalation, on x86 (amd64 and     i386) and possibly other architectures.
