FKIE_CVE-2024-4420

Vulnerability from fkie_nvd - Published: 2024-05-21 12:15 - Updated: 2025-06-05 14:41
Severity
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
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

Esto fallar\u00e1 ya que Tink simplemente asume que cualquier entrada JSON v\u00e1lida contendr\u00e1 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.
