CVE-2022-42969 (GCVE-0-2022-42969)

Vulnerability from cvelistv5 – Published: 2022-10-16 00:00 – Updated: 2025-05-14 14:15 Disputed
VLAI
Summary
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.
