      "value": "xrdp is an open source RDP server. Versions through 0.10.5 contain a heap-based buffer overflow vulnerability in its logon processing. In environments where domain_user_separator is configured in xrdp.ini, an unauthenticated remote attacker can send a crafted, excessively long username and domain name to overflow the internal buffer. This can corrupt adjacent memory regions, potentially leading to a Denial of Service (DoS) or unexpected behavior. The domain_name_separator directive is commented out by default, systems are not affected by this vulnerability unless it is intentionally configured. This issue has been fixed in version 0.10.6."

      "value": "xrdp es un servidor RDP de código abierto. Las versiones hasta la 0.10.5 contienen una vulnerabilidad de desbordamiento de búfer basado en montículo en su procesamiento de inicio de sesión. En entornos donde domain_user_separator está configurado en xrdp.ini, un atacante remoto no autenticado puede enviar un nombre de usuario y un nombre de dominio manipulados y excesivamente largos para desbordar el búfer interno. Esto puede corromper regiones de memoria adyacentes, lo que podría llevar a una Denegación de Servicio (DoS) o a un comportamiento inesperado. La directiva domain_name_separator está comentada por defecto, los sistemas no se ven afectados por esta vulnerabilidad a menos que se configure intencionalmente. Este problema ha sido solucionado en la versión 0.10.6."
