RHEL 2.1 / 3 : ethereal (RHSA-2004:136)

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

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

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 CVE-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 CVE-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 CVE-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.
