Gnupg incorrect malformed message verification

Tavis Ormandy discovered that it is still possible to trick gnupg into
incorrectly verifying a signed message.

The patch is here:
ftp://ftp.gnupg.org/gcrypt/gnupg/gnupg-1.4.2.1-1.4.2.2.diff.bz2


This issue also affects RHEL3
This issue also affects RHEL2.1

Demo reproducer

This reproducer was given to us by Gentoo.

In order to reproduce this issue on RHEL, the --ignore-crc-error option must be
given to gpg.  This also mitigates the usefullness of this issue on RHEL.
