I am a bit lame - I use PGP, not GPG. But for those who prefer the free version, Bruce Schneier is spreading the word of a bug in the open source email encryption program, including the fixes you should look for.

For those now fretting, it sounds as thought the bug affected signed messages, so I think the dirty little secrets you are passing on (madly scrambled) are still safe. Someone please correct me if I’m wrong.
