Zero Day Initiative Advisory 11-231 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple QuickTime Player. 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 parses a Matrix structure within a particular opcode embedded within a .pict file. When using this Matrix structure to transform image data, the application will miscalculate an index to represent a row of an object. This will cause the application to write outside the bounds of the array of objects which can lead to code execution under the context of the application.

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 performs a transformation on an image sample using the sprite handler. When performing the transformation, the application will scale the sprite outside the bounds of the original buffer. This can cause memory corruption which can lead to code execution within the context of the application.
