CVE-2014-4678

The safe_eval function in Ansible before 1.6.4 does not properly restrict the code subset, which allows remote attackers to execute arbitrary code via crafted instructions. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-4657.

Weakness

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
