RHSA-2002:121: tcpdump security update
Description
Updated tcpdump, libpcap, and arpwatch packages are available. These updates close a buffer overflow when handling 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 CAN-2002-0380 to this issue. This issue was found by David Woodhouse of Red Hat.
