arpwatch, libpcap, tcpdump security update

CentOS Errata and Security Advisory CESA-2005:417

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.
