-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Apple's Webkit. User interaction is required
in that a user must be coerced into viewing a website.

The specific flaw exists within the way the library handles selections.
If a particular element is selected by the application, an event can be
triggered in order to interrupt execution handling a component of the
selection. By modification of the elements contained in the selection by
the interruption, an attacker can substitute contents of their own
choosing in their place. This type switch can lead to code execution
under the context of the application.

-- Vendor Response:
Apple has issued an update to correct this vulnerability. More
details can be found at:
