Name of the Vulnerable Software and Affected Versions: yaml-rust versions 0.4.0 and earlier

Description: The issue is related to uncontrolled recursion, which can lead to a denial of service due to an impossible to catch abort. This occurs when the YamlLoader::load from str function is used to parse a malicious YAML document.

Recommendations: For yaml-rust versions 0.4.0 and earlier, update to version 0.4.1 or later to resolve the issue. As a temporary workaround, consider restricting the use of the YamlLoader::load from str function when parsing untrusted YAML documents.
