               Fedora Legacy Update Advisory

Synopsis:          Updated tcpdump resolves security vulnerability
Advisory ID:       FLSA:1222
Issue date:        2004-01-31
Product:           Red Hat Linux
Keywords:          Security
Cross references:  https://bugzilla.fedora.us/show_bug.cgi?id=1222
CVE Names:         CAN-2003-0989, CAN-2004-0055, CAN-2004-0057
- - -----------------------------------------------------------------------

1. Topic:

Updated tcpdump packages are now available that fix multiple security 
vulnerabilities which may allow remote attackers to exploit these issues 
by sending carefully-crafted packets to a victim. If the victim uses 
tcpdump, these packets could result in a denial of service, or possibly 
execute arbitrary code as the 'pcap' user.

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:

Tcpdump is a command-line tool for monitoring network traffic. Tcpdump can 
capture and display the packet headers on a particular network interface 
or on all interfaces. Tcpdump can display all of the packet headers, or 
just the ones that match particular criteria.

George Bakos discovered flaws in the ISAKMP decoding routines of tcpdump 
versions prior to 3.8.1. The Common Vulnerabilities and Exposures project 
(cve.mitre.org) has assigned the name CAN-2003-0989 to this issue.

Jonathan Heusser discovered an additional flaw in the ISAKMP decoding 
routines for tcpdump 3.8.1 and earlier. The Common Vulnerabilities and 
Exposures project (cve.mitre.org) has assigned the name CAN-2004-0057 to 
this issue.

Jonathan Heusser discovered a flaw in the print_attr_string function in the 
RADIUS decoding routines for tcpdump 3.8.1 and earlier. The Common 
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the 
name CAN-2004-0055 to this issue.

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

Fedora Legacy would like to thank George Bakos and Jonathan Heusser for 
discovering and disclosing these issues, as well as 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>
