Description SMASH SMASH 2024-02-21 15:06:46 UTC 
Use a determistic name when extracting content from GPG
  artifacts instead of trusting the value of gpg's --use-embedded-filenames.

  This prevents a potential information disclosure vulnerability that could
  have been exploited by providing a specially-crafted GPG file with an
  embedded filename of, say, "../../.ssh/id_rsa".

  Many thanks to Daniel Kahn Gillmor <dkg@debian.org> for reporting this
  issue and providing feedback.
