Description Marcel Holtmann 2007-08-01 15:56:57 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 2007-11-14 09:25:11 UTC

A patch for this issue has been included in build 2.4.21-53.EL.
