Apple QuickTime contains an integer overflow vulnerability in the "QuickTime.qts" extension, which could result in arbitrary code execution.
Apple's QuickTime Player is a player that allow users to view local and remote audio/video content. Other applications, such as web browsers, that wish to utilize QuickTime functionality must use the QuickTime extension (QuickTime.qts) component. This component contains an integer overflow vulnerability in the routine responsible for copying Sample-to-Chunk table entries into an array.
According to the QuickTime File Format specification, a Sample-to-Chunk atom contains a 4-byte "number of entries" field specifying the count of entries in the sample-to-chunk-table. If the "number of entries" field contains an overly large value, an integer overflow could occur, which could allow an attacker to overwrite portions of heap memory.
By convincing a user to execute a specially crafted QuickTime file, an attacker could cause QuickTime to crash or potentially execute arbitrary code.
