Description

In freewvs before 0.1.1, a directory structure of more than 1000 nested directories can interrupt a freewvs scan due to Python's recursion limit and os.walk(). This can be problematic in a case where an administrator scans the dirs of potentially untrusted users. This has been patched in 0.1.1.

Affected products

• schokokeksorg freewvs: before 0.1.1 — fixed in 0.1.1

How to fix

Upgrade to a fixed version: schokokeksorg freewvs 0.1.1. Check the vendor advisory for mitigations.
