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 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)

Andy Whitcroft discovered a that the Overlayfs filesystem was not doing the
extended permission checks needed by cgroups and Linux Security Modules
(LSMs). A local user could exploit this to by-pass security policy and
access files that should not be accessible. (CVE-2012-0055)

Juri Aedla discovered that the kernel incorrectly handled /proc/<pid>/mem
permissions. A local attacker could exploit this and gain root privileges.
(CVE-2012-0056)

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)");
