Researchers are warning that there is an security vulnerability affecting two email security protocols: S/MIME and the granddaddy of all email encryption standards, PGP.

The big picture: Details are scant at this point, and the report on the vulnerability will not be released until early tomorrow morning. But the report has been verified by the Electronic Frontier Foundation, which advises that all users turn PGP off.
