The remote host is missing an update to trr19 announced via advisory DSA 430-1.

Steve Kemp discovered a problem in trr19, a type trainer application for GNU Emacs, which is written as a pair of setgid() binaries and wrapper programs which execute commands for GNU Emacs. However, the binaries don't drop privileges before executing a command, allowing an attacker to gain access to the local group games. For the stable distribution (woody) this problem has been fixed in version 1.0beta5-15woody1. The mipsel binary will be added later. For the unstable distribution (sid) this problem will fixed soon. We recommend that you upgrade your trr19 package.
