NVD Description

Note: Versions mentioned in the description apply only to the upstream 389-ds package and not the 389-ds package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

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.
