Description Josh Bressers 2007-03-14 21:10:56 UTC

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.

This flaw also affects RHEL 3 and RHEL4.  The code in question is not present in
RHEL 2.1
