"A vulnerability was discovered in the PyYAML library in versions before 5.3.1, where it is susceptible to arbitrary code execution when it processes untrusted YAML files through the full_load method or with the FullLoader loader. Applications that use the library to process untrusted input may be vulnerable to this flaw. An attacker could use this flaw to execute arbitrary code on the system by abusing the python/object/new constructor."
@maintainer(s), please advise if 5.3.1 is ready for stabilisation, or call yourself.
It's a minor release, so I suppose we can stabilize it earlier.

@maintainer(s), please cleanup
GLSA Vote: No
Please drop vulnerable versions
Bug 714866 is not blocking cleanup (anymore, fixed since bug 708682). Also, this vulnerability affects pyyaml-5.1+ only. From this bug it's not required to cleanup =3.13.
