Description Sam James archtester Gentoo Infrastructure gentoo-dev Security 2024-08-27 01:14:09 UTC 
From the 275 release notes:
"""
* Do not call marshal.loads(...) of precompiled Python bytecode as it is
  inherently unsafe. Replace, at least for now, with a brief summary of the
  code section of .pyc files. (Re: reproducible-builds/diffoscope#371)
