May 17, 2022 (updated February 9, 2024)

The password_checker function in config/multiconfig.py in MoinMoin 1.6.1 uses the cracklib and python-crack features even though they are not thread-safe, which allows remote attackers to cause a denial of service (segmentation fault and crash) via unknown vectors.
