TippingPoint™ IPS Customer ProtectionTippingPoint IPS customers are protected against this vulnerability by Digital Vaccine protection filter ID 10835. For further product information on the TippingPoint IPS:
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 application's implementation of an image format supported by the Universal 3D compressed file format. When decoding the image data provided by the file, the application will use one size for allocating space for the destination buffer and then trust the data when decompressing into that buffer. Due to the decompression being unbounded by the actual buffer size, a buffer overflow can be made to occur leading to code execution under the context of the application.
