Synopsis
========
A flaw in the decoding of network packets in tcpdump allows remote
attackers to cause a denial of service (infinite loop)

Background
==========
tcpdump is CLI packet sniffer network debugging tool

Description
===========
CAN-2005-1267
(From Gentoo: ) While working on the recent tcpdump issues
(CAN-2005-1278, CAN-2005-1279, and CAN-2005-1280) Simon L. Nielsen from
FreeBSD Security Team discovered that there is another similar infinite
loop DoS vulnerability in the BGP handling code.

Affected packages
=================
tcpdump 1.8.3, present in devel, test, stable-rc and stable, is affected
; this is now fixed in all grimoires.

Resolution

All tcpdump users should upgrade to the latest available version:
#scribe update
#cast -c tcpdump
