    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.

    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
    footer to the proper configuration.
