Greetings all,

I came upon something a bit odd in gnupg 1.4.7. I found I can change the 
comment field in a signed message to be whatever I like. I should think this is 
a bad thing as an attacker could insert text in a message presumably protected 
against all modifications if the signature verifies properly.

I'm hoping the attachments won't be corrupted by my emailer. The first 
attachment is the clearsigned message. I altered the comment field manually 
after creating the .asc. The second attachment is the public key so you can 
verify that the clearsigned message is valid.

Thanks loads to everyone whos worked on gnupg. It's a brilliant app and an 
important one at that.

Cheers,
Rand
