Description

Updated tcpdump, libpcap, and arpwatch packages fix vulnerabilities in ISAKMP and RADIUS parsing. [Updated 15 Jan 2004] 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 this issue. 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.
