Hi, The following vulnerability was published for 389-ds-base. At time of writing only the bugzilla entry from Red Hat was known to me. CVE-2026-18663[0]: | A flaw was found in 389-ds-base. The get_ldapmessage_controls_ext() | function frees the parsed controls array on the Session Tracking | critical-control rejection path without clearing the | SLAPI_REQCONTROLS pblock slot. Operation teardown then frees the | same pointer again, causing a double-free. An unauthenticated remote | attacker can trigger this with a single BIND request carrying a | critical Session Tracking control, resulting in heap corruption and | potential denial of service. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
