DESCRIPTION

* CVE-2011-1927: Remote denial of service in ICMP.

In the icmp_send function in net/ipv4/icmp.c, a parameter passed to
the dev_net function is not properly validated.  A remote attacker can
exploit this to cause denial of service via NULL pointer dereference.


* CVE-2011-0716: Memory corruption in IGMP bridge snooping.

IGMP packets sent on a bridged interface could cause corruption
in 512-byte slabs, most commonly leading to crashes in jbd2.


* CVE-2011-3619: Null pointer dereference in AppArmor.

A NULL pointer dereference flaw was found in the Linux kernel's AppArmor
audit logging code. An attacker could exploit this to cause a denial of
service.
