JLSEC-2026-243 Issue summary: A bug has been identified in the processing of key and initialisation vector (IV)...

Issue summary: A bug has been identified in the processing of key and initialisation vector IV lengths. This can lead to potential truncation or overruns during the initialisation of some symmetric ciphers. Impact summary: A truncation in the IV can result in non-uniqueness, which could result in...

libssh: Invalid return code for chacha20 poly1305 with OpenSSL backend

A flaw was found in libssh when using the ChaCha20 cipher with the OpenSSL library. If an attacker manages to exhaust the heap space, this error is not detected and may lead to libssh using a partially initialized cipher context. This occurs because the OpenSSL error code returned aliases with th...

AZL-64797 CVE-2025-5987 affecting package libssh for versions less than 0.10.6-2

A flaw was found in libssh when using the ChaCha20 cipher with the OpenSSL library. If an attacker manages to exhaust the heap space, this error is not detected and may lead to libssh using a partially initialized cipher context.

Vulnerability of the functions EVP_EncryptInit_ex2(), EVP_DecryptInit_ex2(), and EVP_CipherInit_ex2() of the OpenSSL cryptographic library, which allows a perpetrator to gain unauthorized access to protected information

The vulnerabilities of the functions EVPEncryptInitex2, EVPDecryptInitex2, and EVPCipherInitex2 in the OpenSSL cryptographic library are related to the absence of necessary encryption steps. Exploiting these vulnerabilities can allow a remote attacker to gain unauthorized access to protected...
