CVE-2007-2172 fib_semantics.c out of bounds access vulnerability
Last modified: 2007-11-30 17:07:43 EST
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.
A patch for this issue has been included in build 2.6.18-8.1.4.el5.
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.
An advisory has been issued which should help the problem
