    2004-03-02
    ---------------------------------------------------------------------
    
    Name        : tcpdump
    Version     : 3.7.2
    Release     : 7.fc1.1
    Summary     : A network traffic monitoring tool.
    Description :
    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 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.
