Attached is an article which is spot on correct about PGP. I really like PGP as a security solution. It is also the gold standard for digital signatures. The vulnerabilities that have been posted are more of a client side implementation issue than anything do to with the PGP protocol security. Easy way to protect yourself? Just disable HTML in your PGP encrypted communications.
