The remote host is missing an update for the 'linux'
package(s) announced via the referenced advisory.
Vulnerability Insight:
It was discovered that a buffer overflow
existed in the Bluetooth stack of the Linux kernel when handling L2CAP
configuration responses. A physically proximate attacker could use this to cause
a denial of service (system crash). (CVE-2017-1000251) It was discovered that
the asynchronous I/O (aio) subsystem of the Linux kernel did not properly set
permissions on aio memory mappings in some situations. An attacker could use
this to more easily exploit other vulnerabilities. (CVE-2016-10044) Baozeng Ding
and Andrey Konovalov discovered a race condition in the L2TPv3 IP Encapsulation
implementation in the Linux kernel. A local attacker could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2016-10200) Andreas Gruenbacher and Jan Kara discovered that the filesystem
implementation in the Linux kernel did not clear the setgid bit during a
setxattr call. A local attacker could use this to possibly elevate group
privileges. (CVE-2016-7097) Sergej Schumilo, Ralf Spenneberg, and Hendrik
Schwartke discovered that the key management subsystem in the Linux kernel did
not properly allocate memory in some situations. A local attacker could use this
to cause a denial of service (system crash). (CVE-2016-8650) Vlad Tsyrklevich
discovered an integer overflow vulnerability in the VFIO PCI driver for the
Linux kernel. A local attacker with access to a vfio PCI device file could use
this to cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2016-9083, CVE-2016-9084) It was discovered that an information leak
existed in __get_user_asm_ex() in the Linux kernel. A local attacker could use
this to expose sensitive information. (CVE-2016-9178) CAI Qian discovered that
the sysctl implementation in the Linux kernel did not properly perform reference
counting in some situations. An unprivileged attacker could use this to cause a
denial of service (system hang). (CVE-2016-9191) It was discovered that the
keyring implementation in the Linux kernel in some situations did not prevent
special internal keyrings from being joined by userspace keyrings. A privileged
local attacker could use this to bypass module verification. (CVE-2016-9604) It
was discovered that an integer overflow existed in the trace subsystem of the
Linux kernel. A local privileged attacker could use this to cause a denial of
service (system crash). (CVE-2016-9754) Andrey Konovalov discovered that the
IPv4 implementation in the Linux kernel did not properly handle invalid IP
options in some situations. An attacker could use this to cause a denial of
service or possibly ex ... Description truncated, for more information please
