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.
