    tcptraceroute is a setuid-root program which drops root privileges after obtaining a file descriptor used for raw packet capture. However, it did not fully relinquish all privileges, and in the event of an exploitable vulnerability, root privileges could be regained.

    Vulnerability  : failure to drop root privileges
    Problem-Type   : local
    Debian-specific: no
    
    tcptraceroute is a setuid-root program which drops root privileges
    after obtaining a file descriptor used for raw packet capture.
    However, it did not fully relinquish all privileges, and in the event
    of an exploitable vulnerability, root privileges could be regained.
    
    No current exploit is known, but this safeguard is being repaired in
    order to provide a measure of containment in the event that an
    exploitable flaw should be discovered.
    
    For the stable distribution (woody) this problem has been fixed in
    version 1.2-2.
    
    The old stable distribution (potato) does not contain a tcptraceroute
    package.
    
    For the unstable distribution (sid) this problem is fixed in version
    1.4-4.
    
    We recommend that you update your tcptraceroute package.
