CVE-2024-4420

There exists a Denial of service vulnerability in Tink-cc in versions prior to 2.1.3. * An adversary can crash binaries using the crypto::tink::JsonKeysetReader in tink-cc by providing an input that is not an encoded JSON object, but still a valid encoded JSON element, for example a number or an array. This will crash as Tink just assumes any valid JSON input will contain an object. * An adversary can crash binaries using the crypto::tink::JsonKeysetReader in tink-cc by providing an input containing many nested JSON objects. This may result in a stack overflow. We recommend upgrading to version 2.1.3 or above

Summary		(es) Existe una vulnerabilidad de denegación de servicio en Tink-cc en versiones anteriores a la 2.1.3. * Un adversario puede bloquear archivos binarios usando crypto::tink::JsonKeysetReader en tink-cc al proporcionar una entrada que no es un objeto JSON codificado, pero que sigue siendo un elemento JSON codificado válido, por ejemplo, un número o una matriz. Esto fallará ya que Tink simplemente asume que cualquier entrada JSON válida contendrá un objeto. * Un adversario puede bloquear archivos binarios usando crypto::tink::JsonKeysetReader en tink-cc al proporcionar una entrada que contiene muchos objetos JSON anidados. Esto puede provocar un desbordamiento de la pila. Recomendamos actualizar a la versión 2.1.3 o superior.
