    Package        : crawl
    Vulnerability  : buffer overflow
    Problem-Type   : local
    Debian-specific: no
    CVE ID         : CAN-2004-0103
    Steve Kemp from the GNU/Linux audit project discovered a problem in
    crawl, another console based dungeon exploration game, in the vein of
    nethack and rogue.  The program uses several environment variables as
    inputs but doesn't apply a size check before copying one of them into
    a fixed size buffer.
    For the stable distribution (woody) this problem has been fixed in
    version 4.0.0beta23-2woody1.
    For the unstable distribution (sid) this problem has been fixed in
    version 4.0.0beta26-4.
    We recommend that you upgrade your crawl package.
