Vulnerability Title
wolfEngine reuses the AES-GCM nonce on every TLS 1.2 / DTLS 1.2 record
Vulnerability Description
wolfEngine before 1.4.1 generates the 8-byte explicit AES-GCM nonce once when the TLS write key is set and never increments it per record. As a result every TLS 1.2 and DTLS 1.2 AES-GCM record within a connection is encrypted under an identical key and nonce pair. Reusing a GCM key and nonce discloses the keystream (the XOR of two ciphertexts equals the XOR of their plaintexts, so one known record recovers the others) and leaks the GHASH authentication key, enabling authentication tag forgery. AES-CCM, TLS 1.3, and non-TLS use of the cipher are not affected.

Vulnerability Title
wolfSSL wolfEngine 加密问题漏洞
Vulnerability Description
wolfSSL wolfEngine是wolfSSL公司的一款具备加密运算功能的引擎软件。 wolfSSL wolfEngine 1.4.1之前版本存在加密问题漏洞,该漏洞源于生成8字节显式AES-GCM nonce时未递增,导致密钥和nonce重用,可能泄露密钥流和GHASH认证密钥,从而伪造认证标签。
