Description Josh Bressers 2007-02-28 21:47:59 UTC

+++ This bug was initially created as a clone of Bug #230456 +++

CoreLabs has reported several flaws in the way gnupg verifies signed messages. 
It is possible to construct a message with injected content and it will appear
to be valid, signed content.

This flaw is most dangerous in the way many mail programs use gnupg to verify
signed and encrypted messages.
