tcpdump security updates are available for Ubuntu Linux 4.10 and 5.04

==========================================================
Ubuntu Security Notice USN-119-1 May 06, 2005
tcpdump vulnerabilities
CAN-2005-1278, CAN-2005-1279, CAN-2005-1280
==========================================================

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 3.8.3-3ubuntu0.1 (for Ubuntu 4.10), or 3.8.3-3ubuntu0.2 (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 GRE, LDP, BGP, and RSVP packets triggered infinite loops in tcpdump, which caused tcpdump to stop working. This could be abused by a remote attacker to bypass tcpdump analysis of network traffic.

Updated packages for Ubuntu 4.10 (Warty Warthog):
