21 May 2024 — 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 ne... • https://github.com/tink-crypto/tink-cc/issues/4 • CWE-116: Improper Encoding or Escaping of Output •

https://notcve.org/view.php?id=CVE-2020-8929
19 Oct 2020 — A mis-handling of invalid unicode characters in the Java implementation of Tink versions prior to 1.5 allows an attacker to change the ID part of a ciphertext, which result in the creation of a second ciphertext that can decrypt to the same plaintext. This can be a problem with encrypting deterministic AEAD with a single key, and rely on a unique ciphertext-per-plaintext. Un manejo inapropiado de caracteres Unicode no válidos en la implementación de Java Tink versiones anteriores a 1.5, permite a un atacant... • https://github.com/google/tink/commit/93d839a5865b9d950dffdc9d0bc99b71280a8899 • CWE-176: Improper Handling of Unicode Encoding •
