               Fedora Legacy Update Advisory

Synopsis:          Updated ethereal resolves security vulnerabilities
Advisory ID:       FLSA:1193
Issue date:        2004-01-31
Product:           Red Hat Linux
Keywords:          Security
Cross references:  https://bugzilla.fedora.us/show_bug.cgi?id=1193
CVE Names:         CAN-2003-1012, CAN-2004-1013
- -----------------------------------------------------------------------

1. Topic:

Updated ethereal packages are now available that fix multiple security 
vulnerabilities which may allow attackers to make Ethereal crash by 
injecting an intentionally malformed packet onto the wire or by convincing 
someone to read a malformed packet trace file. It is not known if these 
issues could allow arbitrary code execution.

2. Relevant releases/architectures:

Red Hat Linux 7.2 - i386
Red Hat Linux 7.3 - i386
Red Hat Linux 8.0 - i386

3. Problem description:

Ethereal is a network traffic analyzer for Unix-ish operating systems.

The SMB dissector in Ethereal before 0.10.0 allows remote attackers to
cause a denial of service via a malformed SMB packet that triggers a
segmentation fault during processing of Selected packets. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2003-1012 to this issue.

The Q.931 dissector in Ethereal before 0.10.0 allows remote attackers to
cause a denial of service (crash) via a malformed Q.931, which triggers a
null dereference. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2003-1013 to this issue.
Users of tcpdump should update to these update packages, which contain a
backported security patch that corrects this issue.

Users of ethereal should update to these update packages, which contain a 
backported security patch that corrects this issue.

Fedora Legacy would like to thank Christian Pearce for providing a 
backported fix for Red Hat Linux 7.2, 7.3, and 8.0.

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/download 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>
