CVE-2026-11792 389-ds-base: 389-ds-base: heap buffer overflow in audit log password masking (create_masked_entry_string)

A heap buffer overflow flaw was found in 389 Directory Server. When audit logging is enabled, the createmaskedentrystring function in auditlog.c copies a fixed-length password mask into a precisely-sized heap buffer without checking available space. If a short cleartext password is logged requiri...
