SUSE Security Announcement – With certain handcraftable signatures GPG was returning a 0 (valid signature) when used on command-line with option –verify. This only affects GPG version 1.4.x, so it only affects SUSE Linux 9.3 and 10.0. Other SUSE Linux versions are not affected. This could make automated checkers, like for instance the patch file verification checker of the YaST Online Update, pass malicious patch files as correct.
