The remote host is missing an update to linux-image-2.6.38-13-generic
announced via advisory USN-1386-1.
Details:
The linux kernel did not properly account for PTE pages when deciding which
task to kill in out of memory conditions. A local, unprivileged could
exploit this flaw to cause a denial of service. (CVE-2011-2498)
A flaw was discovered in the TOMOYO LSM's handling of mount system calls.
An unprivileged user could oops the system causing a denial of service.
(CVE-2011-2518)
Han-Wen Nienhuys reported a flaw in the FUSE kernel module. A local user
who can mount a FUSE file system could cause a denial of service.
(CVE-2011-3353)
A bug was discovered in the Linux kernel's calculation of OOM (Out of
memory) scores, that would result in the wrong process being killed. A user
could use this to kill the process with the highest OOM score, even if that
process belongs to another user or the system. (CVE-2011-4097)
A flaw was found in KVM's Programmable Interval Timer (PIT). When a virtual
interrupt control is not available a local user could use this to cause a
denial of service by starting a timer. (CVE-2011-4622)
A flaw was discovered in the XFS filesystem. If a local user mounts a
specially crafted XFS image it could potential execute arbitrary code on
the system. (CVE-2012-0038)
Chen Haogang discovered an integer overflow that could result in memory
corruption. A local unprivileged user could use this to crash the system.
(CVE-2012-0044)
A flaw was found in the linux kernels IPv4 IGMP query processing. A remote
attacker could exploit this to cause a denial of service. (CVE-2012-0207)
