A flaw was found in 389 Directory Server. An unauthenticated remote attacker can inject LDAP search filters into the CleanAllRUV replication status-check extended operation. Because the handler performs the search against cn=config with elevated replication plugin privileges and returns a boolean match result, the attacker can extract sensitive server configuration metadata, including replication bind DNs and password storage scheme information.

Because the handler performs the search against cn=config with elevated replication plugin privileges and returns a boolean match result, the attacker can extract sensitive server configuration metadata, including replication bind DNs and password storage scheme information.

• CVE-2026-11770: require an authorised replication bind DN for the CleanAllRUV extended operations and reject unexpected filters in the check-status payload
• CVE-2026-11788: check the result of ber_init() before use in the deref control plugin to avoid a NULL pointer dereference
• CVE-2026-15722: bound the replica id copy in get_ruvelement_from_berval to prevent a stack buffer overflow

• CVE-2026-11788: null-check ber_init failure in the deref control parser
• CVE-2026-11770: fix pre-auth LDAP filter injection in CleanAllRUV extended ops
• Issue-6929-Compilation-failure-with-rust-1.89.patch: fix build: make the ValueArrayRefIter lifetime explicit for rust 1.89+

These are all security issues fixed in the 389-ds-3.3.1+8c2711bd6-1.1 package on the GA media of openSUSE Tumbleweed.

This update for 389-ds fixes the following issues:

• CVE-2026-18453: 389-ds-base: 389-ds-base: pre-authentication NULL pointer dereference via paged results and USE_ONE_BACKEND control in op_shared_search (bsc#1279572).
• CVE-2026-18922: stale identity carried in a Cyrus SASL auxiliary property during SASL PLAIN authentication allows unauthenticated attackers to achieve privilege escalation to Directory Manager (bsc#1279865).
• CVE-2026-19843: unescaped LDAP DN in Cockpit 389 Console LDAP editor allows an LDAP user with delegated privileges to execute shell commands with root privileges on the directory server host (bsc#1279866).
• CVE-2026-76560: incorrect matching in the SELFDN ACI bind-rule evaluator allows an anonymous LDAP client to bypass access controls on directory entries containing empty SELFDN attributes (bsc#1279867).
