      • Report NetzDG Violation

      Hector Martin Retweeted EFF

      This sounds like multiple RCE issues in common PGP and S/MIME software, but the details are vague so far. Or it could be a side channel issue. Hmm.https://twitter.com/EFF/status/995906839958061056 …

      Hector Martin added,

      EFFVerified account @EFF
      A new security vulnerability has been discovered in PGP (and GPG) that affects a range of email clients and plugins. To protect yourself, EFF highly recommends that for now you uninstall or disable your PGP email plug-in. #efail 1/4 https://www.eff.org/deeplinks/2018/05/attention-pgp-users-new-vulnerabilities-require-you-take-action-now …

      "might reveal the plaintext of encrypted emails, including encrypted emails sent in the past" makes me think it's some nasty cryptographic issue; if it was RCE you'd think we'd be seeing a patch instead of "just disable it"

      plus, hard to imagine an implementation bug that affects all these email clients, but _nothing else_ using PGP

      The only reasonable nasty cryptographic issue that fits the advice is a key disclosure side channel problem (receive encrypted email, somehow leaks part of your decryption key back).

      or something leaking _in outbound emails_

      They specifically mentioned automatic decryption in the post. > immediately disable and/or uninstall tools that automatically decrypt PGP-encrypted email.

      oh welp but if it was RCE you'd think there'd be a bigger fuss than "it could be used to decrypt existing emails", and "if you use PGP to handle very sensitive communications"?

      I'm basically assuming all vulns are disclosed incompetently these days. Especially those coming from academics.
