Doh, I had for some reason not thought of that.  It seems like there
is p5-Crypt-OpenPGP, security/pgpin, security/pgp, and security/pgp6
which are not just frontends.

From a quick check of the pgp 2.6.3 docs it seems to also support CFB
so I would think it is also vulnerable.

All the projects seems to be rather dead (no activity for 3+ years)...

Should a comment about this be added to the VuXML entry?  I think it
seems like a bit of overkill to mark the recent gnupg still vulnerable
due to the _very_ low likeliness that anyone is impacted.
