Descriptions

Heap-based buffer overflow in Microsoft Remote Desktop Connection (formerly Terminal Services Client) running RDP 5.0 through 6.1 on Windows, and Remote Desktop Connection Client for Mac 2.0, allows remote attackers to execute arbitrary code via unspecified parameters, aka "Remote Desktop Connection Heap Overflow Vulnerability."

Desbordamiento de búfer basado en memoria dinámica en la conexión remota de escritorio de Microsoft (anteriormente Terminal Services Client) cuando corre RDP desde v5.0 hasta v6.1 en Windows, y Cliente de escritorio remoto para Mac 2.0, permite a atacantes remotos ejecutar código arbitrario a través de parámetros sin especificar, también conocido como "Vulnerabilidad de memoria dinámica en la conexión de escritorio remoto"

This vulnerability allows attackers to execute arbitrary code on vulnerable installations of Microsoft's Remote Desktop Client. Authentication is not required to exploit this vulnerability.
The specific flaw exists within mstscax.dll when parsing packets from an RDP server. A design flaw in the client allows a malicious RDP server to write to arbitrary memory inside the connecting processes memory space. By hosting a malicious RDP server, an attacker can execute arbitrary code on any client that attempts to connect to it. Privileges gained depend on which user is running the client.
