Mandriva Linux Security Advisory 2013-186

Description : Mandriva Linux Security Advisory 2013-186 - Updated puppet packages fix remote code execution vulnerability. When making REST api calls, the puppet master takes YAML from an untrusted client, deserializes it, and then calls methods on the resulting object. A YAML payload can be crafted to cause the deserialization to construct an instance of any class available in the ruby process, which allows an attacker to execute code contained in the payload.

 Problem Description:

 Updated puppet packages fix remote code execution vulnerability

 When making REST api calls, the puppet master takes YAML from
 an untrusted client, deserializes it, and then calls methods on
 the resulting object. A YAML payload can be crafted to cause the
 deserialization to construct an instance of any class available in
 the ruby process, which allows an attacker to execute code contained
 in the payload (CVE-2013-3567).
