Technical details
A heap-based buffer overflow vulnerability exists in the Remote Desktop Client that allows remote code execution over the network. The vulnerability is reachable without authentication, meaning an attacker on the network can trigger the overflow by sending a specially crafted RDP protocol message. The buffer overflow condition allows an attacker to overwrite heap memory and achieve arbitrary code execution with the privileges of the user running the client. A fix from Microsoft is expected to be available through Windows Update or the Microsoft Security Update Guide.
