Fedora Core 1 2004-090: tcpdump

Vulnerability Assessment Summary Check for the version of the tcpdump package Detailed Explanation for this Vulnerability Assessment The remote host is missing the patch for the advisory FEDORA-2004-090 (tcpdump). Tcpdump is a command-line tool for monitoring network traffic. Tcpdump can capture and display the packet headers on a particular network interface or on all interfaces. Tcpdump can display all of the packet headers, or just the ones that match particular criteria. Install tcpdump if you need a program to monitor network traffic. Update Information: Updated tcpdump, libpcap, and arpwatch packages fix vulnerabilities in ISAKMP and RADIUS parsing. 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 CVE-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 CVE-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 CVE-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.
