Descriptions

Use-after-free vulnerability in Microsoft Office 2007 SP2 and SP3, Office 2010 Gold and SP1, and Office for Mac 2011 allows remote attackers to execute arbitrary code via a crafted Word document, aka "Word Use After Free Vulnerability."

Una vulnerabilidad de uso después de liberación en Microsoft Office 2007 SP2 y SP3, Office 2010 Gold y SP1, y Office 2011 para Mac permite a atacantes remotos ejecutar código de su elección a través de un documento de Word específicamente modificado para tal fin. Se trata de un problema también conocido como "vulnerabilidad de uso después de liberación de Microsoft Word".

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Office Word 2007/2010. 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 how the application handles a border containing a specific property. When parsing this property, the application will incorrectly free it. If the application attempts to render the object, a use-after-free condition can be made to occur. This can lead to code execution under the context of the application.
