Seems to be a set of MUA bugs that are being overblown and hyped up.

TL;DR = Don't use HTML email with some mail clients when sending pgp

    This is likely bad enough operators need to pay attention.

    @seecurity tweeted:

    "We'll publish critical vulnerabilities in PGP/GPG and S/MIME email
encryption on 2018-05-15 07:00 UTC. They might reveal the plaintext of
encrypted emails, including encrypted emails sent in the past. #efail 1/4"

    I have no particular insight into what it is other than presuming from
thread that decryption can be tricked to do bad things.

    They recommend temporary disabling downthread:

    "There are currently no reliable fixes for the vulnerability. If you
use PGP/GPG or S/MIME for very sensitive communication, you should disable
it in your email client for now. Also read @EFF’s blog post on this issue:
eff.org/deeplinks/2018… #efail 2/4"
