    Package : lbreakout2
    Vulnerability : buffer overflow
    Problem-Type : local
    Debian-specific: no
    CVE Ids : CAN-2004-0158

    During an audit, Ulf Harnhammar discovered a vulnerability in
    lbreakout2, a game, where proper bounds checking was not performed on
    environment variables. This bug could be exploited by a local
    attacker to gain the privileges of group "games".

    For the current stable distribution (woody) this problem has been
    fixed in version 2.2.2-1woody1.

    For the unstable distribution (sid), this problem will be fixed soon.

    We recommend that you update your lbreakout2 package.

    Upgrade Instructions
    - --------------------

    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.

    sources.list as given below:

    apt-get update
