Summary

Jonathan Gray and Stanislaw Pitucha found an assertion failure in the way wrapped strings are parsed in LibYAML, a fast YAML 1.1 parser and emitter library. An attacker able to load specially crafted YAML input into an application using libyaml could cause the application to crash. This update corrects this flaw in the copy that is embedded in the libyaml-libyaml-perl package.
