Tavis Ormandy noticed that gnupg, the GNU privacy guard - a free PGP replacement, can be tricked to emit a ‘good signature’ status message when a valid signature is included which does not belong to the data packet. This update basically adds fixed packages for woody whose version turned out to be vulnerable as well.
