Update
======

While working on the tcpdump issues solved in the original version of
this GLSA, Simon L. Nielsen from FreeBSD Security Team discovered a
similar infinite loop DoS vulnerability in the BGP handling code
(CAN-2005-1267). New packages have been released to address this new
issue.

The updated sections appear below.

Affected packages
=================

    -------------------------------------------------------------------
     Package               /  Vulnerable  /                 Unaffected
    -------------------------------------------------------------------
  1  net-analyzer/tcpdump     < 3.8.3-r3                   >= 3.8.3-r3

Description
===========

TCPDump improperly handles and decodes ISIS (CAN-2005-1278), BGP
(CAN-2005-1267, CAN-2005-1279), LDP (CAN-2005-1279) and RSVP
(CAN-2005-1280) packets. TCPDump might loop endlessly after receiving
malformed packets.

Resolution
==========

All TCPDump users should upgrade to the latest available version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-analyzer/tcpdump-3.8.3-r3"
