Background
Snakeyaml is a popular Java library for parsing YAML files. It provides a simple and efficient way to handle YAML data in Java applications. However, versions prior to 1.32 are vulnerable to a stack overflow vulnerability that can be exploited by an attacker to cause a denial of service (DOS) attack. This vulnerability occurs when the parser is used to parse untrusted YAML files, allowing an attacker to supply content that triggers a stack overflow and crashes the parser.
