CVE-2026-11792
Full vulnerability record from the local CVENow database.
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.

"value": "Se encontró una vulnerabilidad de desbordamiento de búfer de montón en 389 Directory Server. Cuando el registro de auditoría está habilitado, la función create_masked_entry_string() en auditlog.c copia una máscara de contraseña de longitud fija en un búfer de montón de tamaño preciso sin verificar el espacio disponible. Si se registra una contraseña corta en texto claro (que requiere almacenamiento de contraseña CLEAR no predeterminado o un par de replicación comprometido), la copia desborda el búfer, corrompiendo la memoria del montón y la salida del registro de auditoría."
