More information:

Steve Kemp from the Debian Security Audit Project discovered a problem in crawl, another console based dungeon exploration game, in the vein of nethack and rogue. The program uses several environment variables as inputs but doesn't apply a size check before copying one of them into a fixed size buffer.

For the stable distribution (woody) this problem has been fixed in version 4.0.0beta23-2woody1.

For the unstable distribution (sid) this problem has been fixed in version 4.0.0beta26-4.

We recommend that you upgrade your crawl package.

Fixed in:

Debian GNU/Linux 3.0 (woody)
