      "value": "xrdp is an open source RDP server. Versions 0.10.6 and prior contain a missing bounds check in xrdp, which allows a heap-based buffer overflow when operating in vnc-any mode. The issue occurs during the handling of RFB protocol color map messages from a VNC server, where incoming color indices are not properly validated. A malicious VNC server can exploit this flaw by sending crafted messages with out-of-range values, leading to an out-of-bounds write on the heap. This memory corruption can result in a denial of service (DoS) or potentially allow remote code execution (RCE) prior to authentication. This issue has been fixed in version 0.10.6.1."

El problema ocurre durante el manejo de mensajes de mapa de colores del protocolo RFB de un servidor VNC, donde los \u00edndices de color entrantes no se validan correctamente. Un servidor VNC malicioso puede explotar esta falla enviando mensajes manipulados con valores fuera de rango, lo que lleva a una escritura fuera de l\u00edmites en el mont\u00edculo. Esta corrupci\u00f3n de memoria puede resultar en una denegaci\u00f3n de servicio (DoS) o potencialmente permitir la ejecuci\u00f3n remota de c\u00f3digo (RCE) antes de la autenticaci\u00f3n.
