Descriptions

Microsoft Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, and Windows 7 SP1 mishandle DLL loading, which allows local users to gain privileges via a crafted application, aka "MAPI DLL Loading Elevation of Privilege Vulnerability."

Microsoft Windows Vista SP2, Windows Server 2008 SP2 y R2 SP1 y Windows 7 SP1 no maneja adecuadamente la carga de DLL, lo que permite a usuarios locales obtener privilegios a través de una aplicación manipulada, también conocido como "MAPI DLL Loading Elevation of Privilege Vulnerability".

This vulnerability allows attackers to execute arbitrary code on vulnerable installations of Microsoft Internet Explorer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the IShdocvwBroker::NewMessage API. Calling this API causes the broker process to load a DLL from a potentially unsafe location. An attacker can leverage this vulnerability to execute code under the context of the user at medium integrity.
