    Package : chbg
    Vulnerability : buffer overflow
    Problem-Type : local
    Debian-specific: no
    CVE ID : CAN-2004-1264
    Debian Bug : 285904

    Danny Lungstrom discoverd a vulnerability in chbg, a tool to change
    background pictures. A maliciously crafted configuration/scenario
    file could overflow a buffer and lead to the execution of arbitrary
    code on the victim's machine.

    For the stable distribution (woody) this problem has been fixed in
    version 1.5-1woody1.

    For the unstable distribution (sid) this problem has been fixed in
    version 1.5-4.

    We recommend that you upgrade your chbg package.
