The remote host is missing an update to gtetrinet announced via advisory DSA 1163-1. Michael Gehring discovered several potential out-of-bounds index accesses in gtetrinet, a multiplayer Tetris-like game, which may allow a remove server to execute arbitrary code.

For the stable distribution (sarge) these problems have been fixed in version 0.7.8-1sarge2. For the unstable distribution (sid) these problems will be fixed soon. We recommend that you upgrade your gtetrinet package. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%201163-1
