## Description:

This update for 389-ds fixes the following issues:

  * CVE-2026-11770: pre-auth LDAP filter injection in CleanAllRUV status check
    (bsc#1273133).
  * CVE-2026-18355: heap buffer overflow in the SASL I/O layer allows a remote
    authenticated attacker to cause a denial of service or potentially achieve
    remote code execution (bsc#1279864).
  * 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
