Description:
eEye Digital Security has discovered a vulnerability in Apple QuickTime, which can be exploited by malicious people to compromise a user's system.
The QuickTime extension ("QuickTime.qts") is a component used by various applications to access QuickTime functionality. The vulnerability is reportedly caused due to an integer overflow within a routine used for copying Sample-to-Chunk table entries from the "stsc" atom data in a QuickTime-format movie (".mov") into an array.
This can be exploited via a specially crafted movie to cause a heap overflow by specifying an overly long value in the "number of entries" field.
According to eEye Digital Security, successful exploitation allows execution of arbitrary code on a user's system. However, the vendor claims that exploitation only causes the application to terminate.
The vulnerability has been reported in the following products:
* Apple QuickTime 6.5
* Apple iTunes 4.2.0.72
Solution:
Update to version 6.5.1.
