First published: Mon Feb 13 2012(Updated: )

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 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) Jüri Aedla discovered that the kernel incorrectly handled /proc//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)
