DESCRIPTION

* Data corruption on Container's live migration.

A race condition could cause data corruption on Container's live
migration.


* CVE-2013-2141: Information leak in tkill() and tgkill() system calls.

Due to a lack of proper initialisation, the tkill() and tgkill() system
calls may leak data from the kernel stack to an unprivileged local user.


* CVE-2013-4470: Memory corruption in IPv4 and IPv6 networking corking with UFO.

The kernel IP stack does not correctly handle sending fragmented packets via a
device which has UDP Fragmentation Offload enabled leading to memory corruption
and a kernel panic.
