DESCRIPTION

* ext4 filesystem corruption on fallocate.

Attempting to fallocate() a file over 4GB with insufficient space on an
ext4 filesystem could result in corruption of the filesystem image.


* CVE-2012-2745: Denial-of-service in kernel key management.

A potential double-free of the replacement session keyring on fork()
could result in a denial-of-service by a local, unprivileged user.


* CVE-2012-2744: Remote denial-of-service in IPv6 connection tracking.

A flaw in the IPv6 connection tracking netfilter module could allow a
remote attacker to trigger a NULL pointer dereference and
denial-of-service with specially crafted IPv6 packets.
