Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      Except for PHP’s insane RFI problem, the web tier vulns as bad as RCE are all shared by C. Even unmarshalling!

      I don't claim C inherently fares better here, just maybe not significantly worse.

      It’s worse! Because in addition to SQLI, file access vulns, and races, you also get memory corruption.

      What additional value does that give an attacker for a webapp with a modern containerized deployment?

      The exact same thing SQLI gives you: game over for that application.

      I am not disputing that SQLI is as bad as RCE. It almost always is.

      I’m saying two game-over vectors is worse than one.

      (incidentally: my faith in “containerization” as protection for losing code execution: not at all high)

      I don't see most use as a "protection"; rather it just makes throwing away & replacing a compromised environment easy.

      Yes, but to do that, you have to trust that the host isn’t compromised, and you probably shouldn’t.

          Sure. But contrast with EC2 virtualization, which most people do sort of trust.
