Description Marcel Holtmann 2007-05-04 02:07:16 UTC 
The Linux kernel is prone to an out-of-bounds-access vulnerability. This issue
occurs because the semantics for IPv4 Forwarding Information Base fail to
adequately bounds-check user-supplied data before accessing an array.

An attacker can exploit this issue to cause denial-of-service conditions.
Arbitrary code execution may also be possible, but this has not been confirmed.
Comment 1 Don Howard 2007-05-07 17:13:23 UTC 
A patch for this issue has been included in build 2.6.18-8.1.4.el5.
Comment 2 Mike Gahagan 2007-05-09 20:08:38 UTC 
Confirmed that the patch is in 2.6.18-8.1.4.el5. I take it there is no known
exploit or other test case for this.
