CVE-2026-14969

389-ds-base: 389-ds-base: static initialization vector in aes-cbc/3des-cbc attribute encryption

A flaw was found in 389-ds-base where the LDBM backend attribute encryption uses a hardcoded static initialization vector for AES-CBC and 3DES-CBC operations, allowing an attacker with privileged filesystem access to detect plaintext equality across encrypted entries by comparing ciphertext blocks.
