1. Topic:

Updated Ethereal packages that fix various security vulnerabilities are now
available.

2. Relevant releases/architectures:

Red Hat Linux 9 - i386

3. Problem description:

Ethereal is a program for monitoring network traffic.

Stefan Esser reported that Ethereal versions 0.10.1 and earlier contain
stack overflows in the IGRP, PGM, Metflow, ISUP, TCAP, or IGAP dissectors.
 On a system where Ethereal is being run a remote attacker could send
malicious packets that could cause Ethereal to crash or execute arbitrary
code.  The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2004-0176 to this issue.

Jonathan Heussser discovered that a carefully-crafted RADIUS packet could
cause a crash.  The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2004-0365 to this issue.

Ethereal 0.8.13 to 0.10.2 allows remote attackers to cause a denial of
service (crash) via a zero-length Presentation protocol selector.  The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CAN-2004-0367 to this issue.

Users of Ethereal should upgrade to these updated packages, which contain
a version of Ethereal that is not vulnerable to these issues.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

Please note that this update is available via Red Hat Network.  To use Red
Hat Network, launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

5. RPMs required:
