> Mar 05, 2007
>
> I. 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. DESCRIPTION
>
> 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.
>
> 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.
>
> III. ANALYSIS
>
> 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.
>
> IV. DETECTION
>
> iDefense Labs confirmed this vulnerability exists in version 7.1.3 of
> QuickTime on Windows. Previous versions are suspected to be
> vulnerable.
