CVE-2024-8088

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.

Weakness

The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop.
