CVE-2026-11792

LOW

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

Title source: cna
STIX 2.1

Description

A heap buffer overflow flaw was found in 389 Directory Server. When audit logging is enabled, the create_masked_entry_string() 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 (requiring non-default CLEAR password storage or a compromised replication peer), the copy overflows the buffer, corrupting heap memory and audit log output.
