Remote Desktop Client Remote Code Execution Vulnerability

Heap-based buffer overflow in Remote Desktop Client allows an unauthorized attacker to execute code over a network.

FAQ

How could an attacker exploit this vulnerability?

An attacker could exploit this vulnerability by persuading a user to connect to a malicious Remote Desktop Protocol (RDP) server using a vulnerable RDP client. The malicious server could send specially crafted responses that trigger memory corruption on the client system, potentially allowing arbitrary code execution in the context of the logged-on user. Successful exploitation requires user interaction to establish the RDP connection.
