Ubuntu 4.10 / 5.04 / 5.10 : gnupg vulnerability (USN-252-1)

Tavis Ormandy discovered a potential weakness in the signature verification of gnupg. gpgv and gpg --verify returned a successful exit code even if the checked file did not have any signature at all. The recommended way of checking the result is to evaluate the status messages, but some third-par...
