Quick fix

PYSEC-2014-24 — django-piston: upgrade to the fixed version with the command below.

pip install --upgrade 'django-piston>=0.2.3'

Details

emitters.py in Django Piston before 0.2.3 and 0.2.x before 0.2.2.1 does not properly deserialize YAML data, which allows remote attackers to execute arbitrary Python code via vectors related to the yaml.load method.
