- ---------------------------------------------------------------------

1. Summary:

Updated tcpdump packages that fix a security issue are now available.

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

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

3. Problem description:

Tcpdump is a command line tool for monitoring network traffic.

A denial of service bug was found in tcpdump during the processing of
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 name CAN-2005-1267 to this issue. 

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

following Web page for the System Administration or Customization
guide specific to your system:
