    Package        : tcpdump
    Vulnerability  : infinite loop
    Problem-Type   : remote
    Debian-specific: no
    CVE Id         : CAN-2003-0093
    
    A problem has been discovered in tcpdump, a powerful tool for network
    monitoring and data acquisition.  An attacker is able to send a
    specially crafted RADIUS network packet which causes tcpdump to enter
    an infinite loop.
    
    For the stable distribution (woody) this problem has been
    fixed in version 3.6.2-2.4.
    
    The old stable distribution (potato) does not seem to be affected
    by this problem.
    
    The unstable distribution (sid) is not affected by this problem anymore.
    
    We recommend that you upgrade your tcpdump package.
