TITLE

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

DESCRIPTION

Heap-based buffer overflow in QuickTimeMPEG.qtx 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 crafted genl atom in a QuickTime movie file with MPEG encoding, which is not properly handled during decompression. 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 MPEG content. Upon reading a field used for compression within a 'genl' atom in the movie container, the application will decompress outside the boundary of an allocated buffer. Successful exploitation can lead to code execution under the context of the application. A heap overflow is caused when QuickTime fails to perform proper bounds checking on the amount of data copied to the heap by a set of nested loops which can result in arbitrary code execution. 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.
