Zero Day Initiative Advisory 10-068 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple QuickTime. User interaction is required in that a target must open a malicious media file or visit a malicious page. The specific flaw exists within the parsing of H.263 media files. The code within QuickTime trusts various values from MDAT structures and uses them during operations on heap memory. By crafting specific values the corruption can be leveraged to execute remote code under the context of the user running 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 quicktime.qts when parsing sample data from a malformed .3g2 file that is utilizing the h.263 codec. While parsing data to render the video stream, the application will miscalculate the length of a buffer. Later when decompressing data to the heap chunk, the application will overflow the under allocated buffer leading to code execution under the context of the currently logged in user.
