CVE-2022-42969
Medium 5.3
In plain English
A medium-severity regular-expression denial of service in the python-py package (Debian). Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 2.1% (higher than 82% of all known vulnerabilities).
Official description
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. Note: This has been disputed by multiple third parties as not being reproduceable and they argue this is not a valid vulnerability.
