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.
