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: https://github.com/schokokeksorg/freewvs/commit/83a6b55c0435c69f447488b791555e6078803143

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.
