Apple QuickTime Color Table ID Heap Corruption Vulnerability
------------------------------------------------------------------------


SUMMARY

<http://www.apple.com/quicktime/> Quicktime is "Apple's media player
product used to render video and other media". Remote exploitation of a
heap corruption vulnerability in Apple Computer Inc.'s QuickTime media
player could allow an attacker to execute arbitrary commands in the
context of the current user.

DETAILS

Vulnerable Systems:
* QuickTime version 7.1.3 for Windows.
* Previous versions are suspected to be vulnerable.

The vulnerability specifically exists in QuickTime players handling of
Video media atoms. When the 'Color table ID' field in the Video Sample
Description is 0, QuickTime expects a color table to be present
immediately after the description. 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.

Exploitation allows an attacker to execute arbitrary code in the context
of the current user.

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.

Vendor Status:
Apple has addressed this vulnerability by releasing version 7.1.5 of
Quicktime.
