"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.
