      This is exactly like saying BEAST and CRIME aren’t attacks on TLS because they depend on browser HTTP to function. https://twitter.com/Julian_Wampfler/status/996056764201172993 …

      Replying to @dakami

      This is like saying an attack on a popular web client that still enables SSLv3 by default is SSL/TLS's fault. I mean, sure, but when the problem has been known for years and updates deployed to fix it...

      That doesn’t seem to be the case here at all.

      Replying to @dakami

      GPG supports MDCs and returns an error when they're suspiciously missing or wrong. We've already gone over the reasons why it can't fail early without returning any plaintext. It's not perfect, but most of the problem here is MUAs, not PGP.

      I'm sure we can argue about just how clear usage requirements were, but when someone takes a decade+ old crypto flaw and uses it together with application logic mistakes and security issues, the correct response isn't "PGP is terrible, broken and doomed, stop using it".

      The entire thing hinges on two scenarios: out of context decryption (100% an application layer problem) and in-context mutation (abuses known malleability problem; ignoring error code from mitigations is an application layer problem) all relying on an app layer back channel.

          PGP shouldn’t have this malleability. Full stop.
