Hi, The following vulnerability was published for 389-ds-base. CVE-2026-11884[0]: | A heap buffer overflow flaw was found in 389 Directory Server. When | serializing objectclass definitions, the oc_superior (SUP) field | length is omitted from buffer size calculations in read_schema_dse() | and schema_oc_to_string(), but the field is still written via | strcat(). An attacker with Directory Manager privileges, or a | compromised replication supplier, can trigger a server crash by | creating objectclasses with long SUP values. This is an incomplete | fix variant of CVE-2025-14905. https://bugzilla.redhat.com/show_bug.cgi?id=2423624 If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
