Summary:
This event is generated when an attempt is made to exploit a known vulnerability in Apple QuickTime.

--
Impact:
Unknown.

--
Detailed Information:
Apple QuickTime is prone to a scripting attack via the use of the HREFTrack parameter in a media file (.mov). A remote attacker could make use of this vulnerability to perform a cross site or cross zone scripting attack against a vulnerable machine.

QuickTime files are composed of a number of tracks, each of which have some sort of (typically media) information in them. One possible track type is the HREF track, which allows a link in any file, web page, or piece of script to call a specific location in a movie.

These tracks take the form in the file of:

A<URL> T<frame>

Where

  * "A" is optional, and if present indicates that the URL is loaded automatically.
  * <URL> is a valid URL of some sort, and may include a "script='foo'" parameter.
  * " T" appears to be static and required
  * <frame> may be blank, but is also required
