Debian: crawl Buffer overflow vulnerability
Summary
Steve Kemp from the GNU/Linux 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.
