This update fixes the following security issues :
* A flaw was found in the way file permission checks for the
'/dev/cpu/[x]/msr' files were performed in restricted root
environments (for example, when using a capability-based security
model). A local user with the ability to write to these files could
use this flaw to escalate their privileges to kernel level, for
example, by writing to the SYSENTER_EIP_MSR register. (CVE-2013-0268,
* A race condition was found in the way the Linux kernel's ptrace
implementation handled PTRACE_SETREGS requests when the debuggee was
woken due to a SIGKILL signal instead of being stopped. A local,
unprivileged user could use this flaw to escalate their privileges.
Users should upgrade to these updated packages, which contain
backported patches to correct these issues. The system must be
rebooted for this update to take effect.
