CVE-2026-11792

CVE-2026-11792 affects 389 Directory Server (389-ds-base). A heap buffer overflow occurs in auditlog.c, in the create_masked_entry_string() function, when audit logging uses a fixed-length password mask and the destination heap buffer lacks sufficient space. If a short cleartext password is logge...
