Description Josh Bressers 2007-03-14 17:16:53 EDT
+++ 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.
