Debian GNU/Linux Advisories: gnupg, trr19

Phong Nguyen identified a severe bug in the way GnuPG creates and uses ElGamal keys for signing. This is a significant security failure which can lead to a compromise of almost all ElGamal keys used for signing.

This update disables the use of this type of key.

For the current stable distribution (woody) this problem has been fixed in version 1.0.6-4woody1.

For the unstable distribution, this problem has been fixed in version 1.2.4-1.

We recommend that you update your gnupg package.

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.
