PYSEC-2020-233

Vulnerability from pysec - Published: 2020-07-14 22:15 - Updated: 2021-08-27 03:22

Details

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.

Vulnerability from github – Published: 2024-08-30 18:43 – Updated: 2024-08-30 18:43

Summary

freewvs's nested directory structure can interrupt scan

Details

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
