PYSEC-2017-78 — confire: upgrade to the fixed version with the command below.
pip install --upgrade 'confire>=8cc86a5ec2327e070f1d576d61bbaadf861597ea'Details
An exploitable vulnerability exists in the YAML parsing functionality in config.py in Confire 0.2.0. Due to the user-specific configuration being loaded from "~/.confire.yaml" using the yaml.load function, a YAML parser can execute arbitrary Python commands resulting in command execution. An attacker can insert Python into loaded YAML to trigger this vulnerability.
