    Problem-Type   : remote
    Debian-specific: no
    CVE Ids        : CAN-2003-0685
    Shaun Colley discovered a buffer overflow vulnerability in netris, a
    network version of a popular puzzle game.  A netris client connecting
    to an untrusted netris server could be sent an unusually long data
    packet, which would be copied into a fixed-length buffer without
    bounds checking.  This vulnerability could be exploited to gain the
    priviliges of the user running netris in client mode, if they connect
    to a hostile netris server.
    For the current stable distribution (woody) this problem has been fixed
    in version 0.5-4woody1.
    For the unstable distribution (sid) this problem is fixed in version
    We recommend that you update your netris package.
