Original Release date: 02 Aug 2006 | Last revised: 02 Aug 2006


A vulnerability in Apple Mac OS X WebKit may allow an attacker to execute arbitrary code on an affected system.



From the OpenDarwin WebKit project description,

    WebKit is an open source web browser engine. WebKit is also the name of the Mac OS X system framework version of the engine that's used by Safari, Dashboard, Mail, and many other OS X applications.

The Problem
Per Apple, an attacker may be able to create a specially crafted HTML document that could cause a previously deallocated object to be accessed.


By convincing a user to view a specially crafted web page or HTML file, a remote, unauthenticated attacker may be able to execute arbitrary code with the privileges of the user or crash the program that opened the malicious document.
