Fedora Legacy Update Advisory
Synopsis: Updated tcpdump packages fix security issues
Advisory ID: FLSA:156139
Issue date: 2006-04-04
Product: Red Hat Linux, Fedora Core
Keywords: Bugfix, Security
CVE Names: CVE-2005-1267, CVE-2005-1278, CVE-2005-1279,
CVE-2005-1280
---------------------------------------------------------------------
---------------------------------------------------------------------
1. Topic:
Updated tcpdump packages that fix several security issues are now
available.
Tcpdump is a command-line tool for monitoring network traffic.
2. Relevant releases/architectures:
Red Hat Linux 9 - i386
Fedora Core 1 - i386
Fedora Core 2 - i386
3. Problem description:
Several denial of service bugs were found in the way tcpdump processes
certain network packets. It is possible for an attacker to inject a
carefully crafted packet onto the network, crashing a running tcpdump
session. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the names CVE-2005-1267, CVE-2005-1278,
CVE-2005-1279, and CVE-2005-1280 to these issues.
Users of tcpdump are advised to upgrade to these erratum packages, which
contain backported security patches and are not vulnerable to 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>
