DESCRIPTION

* CVE-2011-4131: Kernel crash in NFSv4.

nfs4_getfacl decoding causes a kernel crash when a server returns more
than 2 GETATTR bitmap words in response to the FATTR4_ACL attribute
request.


* 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.


* Kernel crash on live migration.

Incorrect ordering between restoring registers and task flags could
result in a kernel crash when migrating between nodes.
