Synopsis:          Moderate: tcpdump security update
Advisory ID:       RHSA-2005:417-02
Advisory URL:      https://access.redhat.com/errata/RHSA-2005:417.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.

This updated package also adds support for output files larger than 2 GB.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - 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.

The tcpdump utility can now write a file larger than 2 GB. 

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:

    up2date
