"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.

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 CVE-2005-1278, CVE-2005-1279,
and CVE-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."
