Zero Day Initiative Advisory 10-261

Zero Day Initiative Advisory 10-261 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple QuickTime. 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 a custom compression algorithm. The application will trust a field within a DirectBitsRect structure which is used for an allocation, and later attempt to decompress data into this buffer. Due to the value for the allocation being different from the length of the data being decompressed a buffer overflow will occur which can lead to code execution with the privileges of the application.

Zero Day Initiative Advisory 10-260

Zero Day Initiative Advisory 10-260 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Quicktime. User interaction is required to exploit this vulnerability in that a user must be coerced into visiting a malicious page or opening a malicious file. The specific flaw exists within Apple's support for Panoramic Images and occurs due to the application trusting a particular field for calculation of an offset. Due to the field being treated as a signed integer, the calculated offset can result in a pointer outside the bounds of the expected buffer. Upon usage of this out-of-bounds pointer, the application will write proceed to write image data to the invalid location. Successful exploitation can lead to code execution under the context of the application.
