Updated the text description to better describe the vulnerabilities found
by Jonathan Heusser and give them CVE names.
Tcpdump is a command-line tool for monitoring network traffic.
George Bakos discovered flaws in the ISAKMP decoding routines of tcpdump
versions prior to 3.8.1. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2003-0989 to this issue.
Jonathan Heusser discovered an additional flaw in the ISAKMP decoding
routines for tcpdump 3.8.1 and earlier. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2004-0057 to
Jonathan Heusser discovered a flaw in the print_attr_string function in the
RADIUS decoding routines for tcpdump 3.8.1 and earlier. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2004-0055 to this issue.
Remote attackers could potentially exploit these issues by sending
carefully-crafted packets to a victim. If the victim uses tcpdump, these
pakets could result in a denial of service, or possibly execute arbitrary
code as the 'pcap' user.
Users of tcpdump are advised to upgrade to these erratum packages, which
contain backported security patches and are not vulnerable to these issues.
