Who is Vulnerable?
Vulnerability Description Safari is a web browsing application developed by Apple. Safari browsing functionality is built around the set of components called WebKit. WebKit is a development toolkit which allows third party developers to build applications that use Internet technologies such as HTML, HTTP, and others. A remote code execution vulnerability has been discovered in Apple Safari's WebKit. The vulnerability is due to an error in WebKit's support for generated content. When utilizing generated content on an element, the vulnerable code inserts multiple references to the generated element. When the generated page is being destroyed the vulnerable application will navigate through the references to discover more elements to destroy. A remote attacker could exploit this vulnerability by enticing the target user to open a maliciously crafted web page. Successful exploitation of this vulnerability will allow an attacker to take complete control of the affected system.
