CVE-2026-33516

xrdp is an open source RDP server. Versions through 0.10.5 contain an out-of-bounds read vulnerability during the RDP capability exchange phase. The issue occurs when memory is accessed before validating the remaining buffer length. A remote, unauthenticated attacker can trigger this vulnerability by sending a specially crafted Confirm Active PDU. Successful exploitation could lead to a denial of service (process crash) or potential disclosure of sensitive information from the process memory. This issue has been fixed in version 0.10.6.

Summary		(es) xrdp es un servidor RDP de código abierto. Las versiones hasta la 0.10.5 contienen una vulnerabilidad de lectura fuera de límites durante la fase de intercambio de capacidades RDP. El problema ocurre cuando se accede a la memoria antes de validar la longitud restante del búfer. Un atacante remoto no autenticado puede activar esta vulnerabilidad enviando una PDU Confirm Active especialmente diseñada. La explotación exitosa podría llevar a una denegación de servicio (caída del proceso) o a la divulgación potencial de información sensible de la memoria del proceso. Este problema ha sido corregido en la versión 0.10.6.
