"Andrew Griffiths and iDEFENSE Labs discovered a problem in tcpdump, a
powerful tool for network monitoring and data acquisition. An attacker
is able to send a specially crafted network packet which causes
tcpdump to enter an infinite loop.

In addition to the above problem the tcpdump developers discovered a
potential infinite loop when parsing malformed BGP packets. They also
discovered a buffer overflow that can be exploited with certain
malformed NFS packets."

tcpdump is a command-line tool for monitoring network traffic.
Versions of tcpdump up to and including 3.6.2 have a buffer overflow
that can be triggered when tracing the network by a bad NFS packet.

We are not yet aware if this issue is fully exploitable; however,
users of tcpdump are advised to upgrade to these errata packages which
contain a patch for this issue.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2002-0380 to this issue. This issue was found by
David Woodhouse of Red Hat."
