    Package        : tcpdump
    Vulnerability  : denial of service
    Problem-Type   : remote
    Debian-specific: no
    CVE Ids        : CAN-2004-0183 CAN-2004-0184
    tcpdump, a tool for network monitoring and data acquisition, was found
    to contain two vulnerabilities whereby tcpdump could be caused to
    crash through attempts to read from invalid memory locations.  This
    bug is triggered by certain invalid ISAKMP packets.
    For the current stable distribution (woody) these problems have been
    fixed in version 3.6.2-2.8.
    For the unstable distribution (sid), these problems have been fixed in
    version 3.7.2-4.
    We recommend that you update your tcpdump package.
