Descriptions

Microsoft .NET Framework 2.0 SP2, 3.5, 3.5.1, 4, and 4.5 does not properly handle function pointers, which allows remote attackers to execute arbitrary code via (1) a crafted XAML browser application (aka XBAP) or (2) a crafted .NET Framework application, aka ".NET Framework Memory Access Vulnerability."

Microsoft .NET Framework v2.0 SP2, v3.5, v3.5.1, v4, y v4.5 no maneja adecuadamente los punteros de función, lo que permite a atacantes remotos ejecutar código arbitrario a través de (1) una aplicación navegador XAML modificada (también conocida como XBAP) o (2) una aplicación basada en el framework .NET modificada, también conocida como "vulnerabilidad .NET Framework de acceso de memoria".

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of the .NET Framework. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The flaw exists within Microsoft .NET XAML Browser Application (XBAP) handling of Clipboard object data. It is possible to cause unsafe memory access within System.Windows.Forms.Clipboard, allowing an attacker to control the memory used by an object's native code. This unsafe access allows for control of a function pointer, which can be exploited to remotely execute code. In the case of Internet Explorer, execution of attacker code occurs outside of the Protected Mode sandbox.
