[de.taimos:pipeline-aws] RCE vulnerability in Jenkins Pipeline: AWS Steps Plugin

Pipeline: AWS Steps Plugin 1.40 and earlier does not configure its YAML parser to prevent the instantiation of arbitrary types. This results in a remote code execution (RCE) vulnerability exploitable by users able to provide YAML input files to Pipeline: AWS Steps Plugin’s build steps.

Pipeline: AWS Steps Plugin 1.41 configures its YAML parser to only instantiate safe types.
