TITLE:
Red Hat update for kernel

SECUNIA ADVISORY ID:
SA39652

VERIFY ADVISORY:
http://secunia.com/advisories/39652/

DESCRIPTION:
Red Hat has issued an update for the kernel. This fixes a
vulnerability, which can be exploited by malicious people to cause a
DoS (Denial of Service).

The vulnerability is caused due to a use-after-free error within the
"tcp_rcv_state_process()" function, which can be exploited to cause a
kernel crash by e.g. sending a specially crafted IPv6 packet to a
listening socket with the IPV6_RECVPKTINFO option enabled.

SOLUTION:
Updated packages are available via Red Hat Network.
