Description Fabio Olive Leite 2007-03-15 21:55:15 UTC

+++ This bug was initially created as a clone of Bug #232347 +++

A potential denial of service flaw due to a single byte overflow was found in
the way tcpdump processes 802.11 packets:
http://seclists.org/fulldisclosure/2007/Mar/0003.html

The upstream patch is here:
http://cvs.tcpdump.org/cgi-bin/cvsweb/tcpdump/print-802_11.c?r1=1.42&r2=1.43

From inspecting our packages it seems that the initial, incorrect test isn't
even present, which still leaves our packages vulnerable to this flaw.

-- Additional comment from bressers on 2007-03-14 17:12 EST --
This flaw also affects RHEL 3 and RHEL4.  The code in question is not present in
RHEL 2.1

Can we get this into 4.6?

Cheers!
