Security Flaw Discovered in GPG

Posted by ryuzaki0 on Thursday March 9, 2006 @02:22PM from the enemy-within dept.

WeLikeRoy writes "A serious problem in the use of GPG to verify digital signatures has been discovered, which also affects the use of gpg in email. It is possible for an attacker to take any signed message and inject extra arbitrary data without affecting the signed status of the message. Depending on how gpg is invoked, it may be possible to output just faked data as several variants of this attack have been discovered. All versions of gnupg prior to 1.4.2.2 are affected, and it is thus recommended to update GnuPG as soon as possible to version 1.4.2.2."

A serious security issue in GPG! We are all doomed!

what is GPG?

Yeah, I will go RTFA. However, summaries that assume you are familiar with an acronym are rude, IMHO ;)

  I have been publishing my GPG key for over a year now and I have yet to have anyone send me an encrypted email. I feel really lonely and unpopular. I'd even read encrypted penis enlargement spam if someone would be thoughtful enough to send me some.

She thought she could get rid of me with that rejection via email. Now I've got reasonable doubt about her feelings. Until I get that court order, of course.

Another good recommendation is to diversify your crypto. Sign/encrypt your data with multiple different crypto algorithms in the same message.
That's an awesome idea. I'm going to start doing that right now! :P
