Description

freewvs's nested directory structure can interrupt scan

Impact

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.

Patches

This has been fixed in this commit by limiting the recursion to 500 directories:
