Ubuntu Security Notice 1969-1 - Vince Weaver discovered a flaw in the perf subsystem of the Linux kernel on ARM platforms. A local user could exploit this flaw to gain privileges or cause a denial of service (system crash). A failure to validate block numbers was discovered in the Linux kernel's implementation of the XFS filesystem. A local user can cause a denial of service (system crash) if they can mount, or cause to be mounted a corrupted or special crafted XFS filesystem. Various other issues were also addressed.

0f9fefdbe51478ae4584a337c802dbed9908e144c668effefb4cb60f45b7d502Red Hat Security Advisory 2013-0829-01 - Security fixes: It was found that the kernel-rt update RHBA-2012:0044 introduced an integer conversion issue in the Linux kernel's Performance Events implementation. This led to a user-supplied index into the perf_swevent_enabled array not being validated properly, resulting in out-of-bounds kernel memory access. A local, unprivileged user could use this flaw to escalate their privileges. A public exploit for CVE-2013-2094 that affects Red Hat Enterprise MRG 2 is available. Refer to Red Hat Knowledge Solution 373743, linked to in the References, for further information and mitigation instructions for users who are unable to immediately apply this update.
