TITLE

Apple Mac OS X of CoreMedia and QuickTime Heap-based buffer overflow vulnerability

DESCRIPTION

Heap-based buffer overflow in quicktime.qts in CoreMedia and QuickTime in Apple Mac OS X before 10.6.3 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a malformed .3g2 movie file with H.263 encoding that triggers an incorrect buffer length calculation. 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. 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 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. Failed exploit attempts will likely result in a denial-of-service condition. NOTE: This issue was previously covered in BID 39020 (Apple Mac OS X APPLE-SA-2010-03-29-1 Multiple Security Vulnerabilities) but has been assigned its own record to better document it. Mac OS X is the operating system used by the Apple family of machines. -- Vendor Response: Apple has issued an update to correct this vulnerability.
