Details

As written in the advisory (Markdown source, shown as plain text).

### 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 This issue was discovered by Hanno Böck.
