    GENTOO LINUX SECURITY ANNOUNCEMENT 200210-005
    - - --------------------------------------------------------------------

    PACKAGE : groff
    SUMMARY : buffer overflow
    DATE    : 2002-10-19 19:30 UTC

    - - --------------------------------------------------------------------

    The groff preprocessor contains an exploitable buffer overflow. If
    groff can be invoked within the LPRng printing system, an attacker
    can gain rights as the "lp" user.

    Remote exploitation may be possible if lpd is running and is accessible
    remotely, and the attacker knows the name of the printer and spoolfile.

    SOLUTION

    It is recommended that all Gentoo Linux users who are running
    sys-apps/groff-1.17.2-r2 and earlier update their systems
    as follows:

    emerge rsync
    emerge groff
    emerge clean
