This is a significant security failure which can lead to a compromise of almost all ElGamal keys used for signing. The update provided in DSA 459-1 disables the use of this type of key, using an interim fix. This update, DSA 459-2, implements a more correct and permanent fix provided by David Shaw. For the current stable distribution (woody) this problem has been fixed in version 1.0.6-4woody3. We recommend that you update your gnupg package. Upgrade Instructions - - -------------------- wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.
