    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.
