Red Hat Security Advisory

Synopsis: Moderate: tcpdump security update
Advisory ID: RHSA-2005:421-02
Advisory URL: https://rhn.redhat.com/errata/RHSA-2005-421.html
Issue date: 2005-05-11
Updated on: 2005-05-11
Product: Red Hat Enterprise Linux
CVE Names: CAN-2005-1278 CAN-2005-1279 CAN-2005-1280
----------------------------------------------------------------------

1. Summary:

Updated tcpdump packages that fix several security issues are now available.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

These updated packages also add support for output files larger than 2 GB, add support for some new VLAN IDs, and fix message parsing on 64bit architectures.



2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Desktop version 3 - i386, x86_64
Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64

3. Problem description:

Tcpdump is a command-line tool for monitoring network traffic.

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 CAN-2005-1278, CAN-2005-1279, and CAN-2005-1280 to these issues.

Additionally, the tcpdump utility can now write a file larger than 2 GB, parse some new VLAN IDs, and parse messages on 64bit architectures.

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 that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command:
