EUVD-2026-42052

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 block...

DEBIAN-CVE-2026-14940

A heap-buffer-overflow flaw was found in 389 Directory Server 389-ds-base. When normalizing a Distinguished Name DN that contains a legacy-quoted value encoding a multivalued nested Relative Distinguished Name RDN, the server can write past the end of a heap allocation while sorting RDN...
