    Package : zblast
    Vulnerability : buffer overflow
    Problem-Type : local
    Debian-specific: no
    CVE Ids : CAN-2003-0613

    Steve Kemp discovered a buffer overflow in zblast-svgalib, when saving
    the high score file. This vulnerability could be exploited by a local
    user to gain gid 'games', if they can achieve a high score.

    For the current stable distribution (woody) this problem has been fixed
    in version 1.2pre-5woody2.

    For the unstable distribution (sid) this problem is fixed in version
    1.2.1-7.

    We recommend that you update your zblast package.
