Quick fix

PYSEC-2009-12 — moin: upgrade to the fixed version with the command below.

pip install --upgrade 'moin>=1.6.1'

Details

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.
