gnupg: GnuPG: Signature bypass via form feed character in signed messages

A flaw was found in GnuPG. An adversary can exploit this vulnerability by crafting a signed message that includes a form feed character \f at the end of a plaintext line. This allows the adversary to append additional, unsigned text to the message while the signature verification still reports...

Fedora Core 4 : gnupg-1.4.2.2-1 (2006-147)

Tavis Ormandy discovered a flaw in the way GnuPG verifies cryptographically signed data with inline signatures. It is possible for an attacker to add unsigned text to a signed message in such a way so that when the signed text is extracted, the unsigned text is extracted as well, appearing as if ...
