CLSA-2026-1785837599 Fix CVE(s): CVE-2026-59847

SECURITY UPDATE: authentication tag verification bypass in the AES-GCM ciphers, allowing forged or tampered packets to be accepted as authentic - debian/patches/CVE-2026-59847.patch: treat an EVPDecryptFinal return value of 0 as an authentication failure reject rc != 1 || outlen != 0 in...

JLSEC-2026-108 Deno's AES GCM authentication tags are not verified

Summary This affects AES-256-GCM and AES-128-GCM in Deno, introduced by commit 0d1beed. Specifically, the authentication tag is not being validated. This means tampered ciphertexts or incorrect keys might not be detected, which breaks the guarantees expected from AES-GCM. Older versions of Deno...

CVE-2026-5479

In wolfSSL's EVP layer, the ChaCha20-Poly1305 AEAD decryption path in wolfSSLEVPCipherFinal and related EVP cipher finalization functions fails to verify the authentication tag before returning plaintext to the caller. When an application uses the EVP API to perform ChaCha20-Poly1305 decryption,...
