CVE-2007-0718

TITLE

Apple QuickTime 3GP integer overflow

DESCRIPTION

Heap-based buffer overflow in Apple QuickTime before 7.1.5 allows remote user-assisted attackers to cause a denial of service (crash) and possibly execute arbitrary code via a QTIF file with a Video Sample Description containing a Color table ID of 0, which triggers memory corruption when QuickTime assumes that a color table exists. The Apple QuickTime player contains a heap buffer overflow vulnerability. This vulnerability may allow an attacker to execute arbitrary code or create a denial-of-service condition. Apple QuickTime is prone to multiple unspecified remote code-execution vulnerabilities including mulitple heap and stack-based buffer-overflow and integer-overflow issues. These issues arise when the application handles specially crafted 3GP, MIDI, MOV, PICT, and QTIF files. Successful attacks can result in the compromise of the applicaiton or can cause denial-of-service conditions. Few details regarding these issues are currently available. Separate BIDs for each issue will be created as new information becomes available. QuickTime versions prior to 7.1.5 are vulnerable. QuickTime is prone to a heap-overflow vulnerability because it fails to perform adequate bounds checking on user-supplied data. There are multiple buffer overflow vulnerabilities in QuickTime's processing of various media formats. Remote attackers may exploit these vulnerabilities to control the user's machine by enticing the user to open and process malformed media files. (CVE-2007-0718). BACKGROUND Quicktime is Apple's media player product used to render video and other media. For more information visit http://www.apple.com/quicktime/ II. The vulnerability specifically exists in QuickTime players handling of Video media atoms. A byte swap process is then performed on the memory following the description, regardless if a table is present or not. Heap corruption will occur in the case when the memory following the description is not part of the heap chunk being processed. III. In order to exploit this vulnerability, an attacker must persuade a victim into opening a specially crafted media file. This could be accomplished by either a direct link or referenced from a website under the attacker's control. No further interaction is required in the default configuration. IV. DETECTION iDefense Labs confirmed this vulnerability exists in version 7.1.3 of QuickTime on Windows. V. WORKAROUND iDefense is currently unaware of any effective workarounds for this vulnerability. VI. More information can be found in Apple Advisory APPLE-SA-2007-03-05 at the following URL. http://docs.info.apple.com/article.html?artnum=305149 VII.
