There is a HIGH severity vulnerability affecting the CPython "zipfile"
module affecting "zipfile.Path". Note that the more common API "zipfile.ZipFile" class is unaffected.
When iterating over names of entries in a zip archive (for example, methods
of "zipfile.Path" like "namelist()", "iterdir()", etc)
the process can be put into an infinite loop with a maliciously crafted
zip archive. This defect applies when reading only metadata or extracting
the contents of the zip archive. Programs that are not handling
user-controlled zip archives are not affected.
