Description Eugene Teo (Security Response) 2009-12-17 20:25:29 EST
Originally discovered by Victor Julien that there is a way to crash the Linux kernel by sending a single IPv6 packet at it.

1) The CVE-2007-4567 issue was reported to Red Hat in September 2007. Red Hat Enterprise Linux 5 was found not to be affected.

2) On December 18, 2009, a customer reported to us that Red Hat Enterprise Linux 5 was vulnerable to CVE-2007-4567.

3) Investigations showed that the issue was introduced in the RHBA-2008-0314 update on May 21, 2008 via a backport of a collection of patches for DoD IPv6 conformance.

4) Updates released on January 7, 2010 for Red Hat Enterprise Linux 5, resolving CVE-2007-4567.

Note that the Linux kernels as shipped with Red Hat Enterprise Linux 3, 4, and Red Hat Enterprise MRG are not affected.
