[USN-141-1] tcpdump vulnerability

===========================================================
Ubuntu Security Notice USN-141-1              June 21, 2005
tcpdump vulnerability
CAN-2005-1267
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)
Ubuntu 5.04 (Hoary Hedgehog)

The following packages are affected:

tcpdump

The problem can be corrected by upgrading the affected package to
version 3.8.3-3ubuntu0.3 (for Ubuntu 4.10), or 3.8.3-3ubuntu0.4 (for
Ubuntu 5.04).  In general, a standard system upgrade is sufficient to
effect the necessary changes.

Details follow:

It was discovered that certain invalid BGP packets triggered an
infinite loop in tcpdump, which caused tcpdump to stop working. This
could be abused by a remote attacker to bypass tcpdump analysis of
network traffic.
