Descriptions

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.

A flaw was found in Python's zipfile module. When iterating over the entries of a zip archive, the process can enter into an infinite loop state and become unresponsive. This flaw allows an attacker to craft a malicious ZIP archive, leading to a denial of service from the application consuming the zipfile module. Only applications that handle user-controlled zip archives are affected by this vulnerability.
