CVE-2022-42969:

The py library through 1.11.0 for Python allows remote attackers to conduct a ReDoS (Regular expression Denial of Service) attack via a Subversion repository with crafted info data, because the InfoSvnCommand argument is mishandled.

No GLSA. Upstream says, "I doubt there's anyone using this code, so I
don't think it would warrant any sort of security notification that
users should bother with, but if you prepare a PR for this I'll merge
& release it."
