Description ybuenos 2024-02-18 12:03:30 UTC

From the 256 release notes:
"""
* CVE-2024-25711: 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> for reporting this
  issue and providing feedback.

  (Closes: reproducible-builds/diffoscope#361)
