CVE-2017-16618 Information

Description

An exploitable vulnerability exists in the YAML loading functionality of util.py in OwlMixin before 2.0.0a12. A \Load YAML\ string or file (aka load_yaml or load_yamlf) can execute arbitrary Python commands resulting in command execution because load is used where safe_load should have been used. An attacker can insert Python into loaded YAML to trigger this vulnerability.
