Zero Day Initiative Advisory 11-075 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Adobe Acrobat Reader. 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 rt3d.dll component explicitly trusting a length embedded within a particular file in order to calculate the length of a buffer. The application will then duplicate an arbitrarily sized string into a statically sized buffer located on the stack. This can lead to code execution under the context of the application.
