An exploitable code execution vulnerability exists in the RDP receive functionality of FreeRDP 2.0.0-beta1+android11. A specially crafted server response can cause an out-of-bounds write resulting in an exploitable condition. An attacker can compromise the server or use a man in the middle to trigger this vulnerability.
The vulnerability is located in the RDP received function of FreeRDP. Similar to the previous vulnerability, the RDP message sent from the server contains a length field, but this field is not verified by the FreeRDP client code. This length can become negative and allows the attacker to execute code on the client side.
