iDefense Security Advisory 01.15.08 http://labs.idefense.com/intelligence/vulnerabilities/ Jan 15, 2008
Quicktime is Apple's media player product, and is used to render video and other media. For more information visit the vendor's web site at the following URL.
Remote exploitation of a heap corruption vulnerability in Apple Computer Inc.'s QuickTime media player could allow attackers to execute arbitrary code in the context of the targeted user.
The vulnerability specifically exists in the handling of Macintosh Resources embedded in QuickTime movies. When processing these records, a length value stored in the resource header is not properly validated. When a length value larger than the actual buffer size is supplied, potentially exploitable memory corruption occurs.
Exploitation of this vulnerability allows attackers to execute arbitrary code in the context of the targeted user. In order to exploit this vulnerability, an attacker must persuade a user into using QuickTime to open a specially crafted QuickTime movie file.
iDefense Labs confirmed this vulnerability exists in QuickTime Player version 7.3.1. Previous versions are suspected to be vulnerable.
iDefense is currently unaware of any effective workaround for this issue.
