CVE-2022-42969

Name of the Vulnerable Software and Affected Versions py versions through 1.11.0

Description The py library 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. This issue is related to the regular expression at py. path.svnurl.InfoSvnCommand.lspattern and is only relevant when dealing with subversion (svn) projects. Note that this issue has been disputed by multiple third parties as not being reproduceable, and they argue this is not a valid vulnerability.

Recommendations For py versions through 1.11.0, consider updating to a version of a dependent package, such as pytest, that removes its dependency on the vulnerable py version, for example, updating to pytest version 7.2.0. At the moment, there is no information about a newer version of py that contains a fix for this issue.
