    Package        : tcpdump
    Vulnerability  : multiple vulnerabilities
    Problem-Type   : remote
    Debian-specific: no
    CVE Ids        : CAN-2003-1029 CAN-2003-0989 CAN-2004-0055 CAN-2004-0057
    Multiple vulnerabilities were discovered in tcpdump, a tool for
    inspecting network traffic.  If a vulnerable version of tcpdump
    attempted to examine a maliciously constructed packet, a number of
    buffer overflows could be exploited to crash tcpdump, or potentially
    execute arbitrary code with the privileges of the tcpdump process.
    CAN-2003-1029 - infinite loop and memory consumption in processing
      L2TP packets
    CAN-2003-0989, CAN-2004-0057 - infinite loops in processing ISAKMP
    CAN-2004-0055 - segmentation fault caused by a RADIUS attribute with a
      large length value
    For the current stable distribution (woody) these problems have been
    fixed in version 3.6.2-2.7.
    For the unstable distribution (sid) these problems will be fixed soon.
    We recommend that you update your tcpdump package.
    Upgrade Instructions
    - --------------------
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
    If you are using the apt-get package manager, use the line for
    sources.list as given below:
    apt-get update
            will update the internal database
    apt-get upgrade
            will install corrected packages
    You may use an automated update by adding the resources from the
