TITLE

Apple Mac OS X of QuickTime Integer overflow vulnerability

DESCRIPTION

Integer overflow in 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 FlashPix image with a malformed SubImage Header Stream containing a NumberOfTiles field with a large value. 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 during the parsing of a malformed SubImage Header Stream from a malicious FlashPix image. The application takes the NumberOfTiles field from this data structure, multiplies it by 16, and then uses it in an allocation. If this result is larger than 32-bits the value will wrap leading to an under-allocated buffer. Later when the application copies data into this buffer, a buffer overflow will occur leading to code execution within the context of the application. Apple QuickTime is prone to an integer-overflow vulnerability when parsing FlashPix encoded files. Successful exploits may allow attackers to execute arbitrary code in the context of the currently logged-in user; failed exploit attempts will cause denial-of-service conditions. The following are vulnerable: Mac OS X 10.6 prior to 10.6.3 Mac OS X Server 10.6 prior to 10.6.3 QuickTime 7 prior to 7.6.6 on Mac OS X 10.5.8 and Microsoft Windows XP, Vista, and 7. 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. An integer overflow vulnerability exists in the handling of FlashPix-encoded movie files in QuickTime versions prior to Apple Mac OS 10.6.3. -- Vendor Response: Apple has issued an update to correct this vulnerability.
