"Description of changes:

* CVE-2012-0207: Denial of service bug in IGMP.

The IGMP subsystem's compatibility handling of v2 packets had a bug in
the computation of a delay field which could result in division by
zero (causing a kernel panic).


* CVE-2012-0045: Denial of service in KVM system call emulation.

A bug in the system call emulation for allowed local users on a 32-bit
KVM guest system to cause the guest system to panic.


* CVE-2012-0038: In-memory corruption in XFS ACL processing.

A missing check in xfs_acl_from_disk on the number of XFS ACLs could
result in in-memory corruption and a kernel panic.


* CVE-2011-4622: NULL pointer deference in KVM interval timer emulation.

Starting PIT timers in the absence of irqchip support could cause a
NULL pointer dereference and kernel OOPs.


* CVE-2011-4347: Denial of service in KVM device assignment.

Several bugs that allowed unprivileged users to improperly assign
devices to KVM guests could result in a denial of service.


* CVE-2011-4132: Denial of service in Journaling Block Device layer.

A flaw in the way the Journaling Block Device (JBD) layer handled an
invalid log first block value allowed an attacker to mount a malicious
ext3 or ext4 image that would crash the system.


* CVE-2011-4081: NULL pointer dereference in GHASH cryptographic algorithm.

Nick Bowler reported an issue in the GHASH message digest
algorithm. ghash_update can pass a NULL pointer to gf128mul_4k_lle in some
cases, leading to a NULL pointer dereference (kernel OOPS).


* CVE-2011-4077: Buffer overflow in xfs_readlink.

A flaw in the way the XFS filesystem implementation handled links with
pathnames larger than MAXPATHLEN allowed an attacker to mount a
malicious XFS image that could crash the system or result in privilege
escalation.
