As bad as the bug is, it doesn't sound like you understood it.
The bug affected signature verification in verbose mode. It doesn't affect encryption, and proving your signature was forged this way would be fairly easy just with the faked signature without knowing the details of the bug ahead of time.
This bug is terrible either way, so why exaggerate it?
