Description Marcel Holtmann 2007-06-08 06:18:20 EDT

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.
