Deserialization of Untrusted Data in org.jboss.resteasy:resteasy-yaml-provider

It was found that the fix for CVE-2016-9606 in versions 3.0.22 and 3.1.2 was incomplete and Yaml unmarshalling in Resteasy is still possible via Yaml.load() in YamlProvider.

Mitigation:

If the YamlProvider is enabled it's recommended to add authentication, and authorization to the endpoint expecting Yaml content to prevent exploitation of this vulnerability.
