1. Topic:

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

Ethereal is a program for monitoring network traffic.

2. Relevent releases/architectures:

Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386

3. Problem description:

Issues fixed with this Ethereal release include:

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.

The MMSE dissector in Ethereal releases 0.10.1 through 0.10.3 contained a buffer overflow flaw. On a system where Ethereal is running, 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-2004-0507 to this issue.

In addition, other flaws in Ethereal prior to 0.10.4 were found that could cause it to crash in response to carefully crafted SIP (CAN-2004-0504), AIM (CAN-2004-0505), or SPNEGO (CAN-2004-0506) packets.

The SNMP dissector in Ethereal releases 0.8.15 through 0.10.4 contained a memory read flaw. On a system where Ethereal is running, a remote attacker could send malicious packets that could cause Ethereal to crash or possibly execute arbitrary code. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2004-0635 to this issue.

The SMB dissector in Ethereal releases 0.9.15 through 0.10.4 contained a null pointer flaw. On a system where Ethereal is running, a remote attacker could send malicious packets that could cause Ethereal to crash. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0634 to this issue.

The iSNS dissector in Ethereal releases 0.10.3 through 0.10.4 contained an integer overflow flaw. On a system where Ethereal is running, a remote attacker could send malicious packets that could cause Ethereal to crash or possibly execute arbitrary code. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2004-0633 to this issue.

Users of Ethereal should upgrade to these updated packages, which contain backported security patches that correct these issues.

4. Solution:

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

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs.

Please note that this update is also available via yum and apt. Many people find this an easier way to apply updates. To use yum issue:

yum update

or to use apt:

apt-get update; apt-get upgrade

This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. This assumes that you have yum or apt-get configured for obtaining Fedora Legacy content. Please visit http://www fedoralegacy.org/docs for directions on how to configure yum and apt-get.

These packages are GPG signed by Fedora Legacy for security. Our key is available from http://www.fedoralegacy.org/about/security.php

You can verify each package with the following command:

rpm --checksig -v filename

If you only wish to verify that each package has not been corrupted or tampered with, examine only the sha1sum with the following command:

sha1sum filename
