VULNERABILITY DETAILS

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Safari's Webkit. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the library's support for mouse events on a particular element. If a mouse event is dispatched to an element when one of it's attributes is undefined, the library will dereference a memory pointer pointing to arbitrary data. Usage of this element can then lead to code execution under the context of the application.
