Vulnerability Description
A remote code execution vulnerability has been discovered in Apple Safari's WebKit. 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 attacker could exploit this issue by convincing a user to open a maliciously crafted HTML, which may allow the attacker to execute arbitrary code on the affected system.
Vulnerability Details
The vulnerability is due to the way Apple Safari's WebKit handles references to attribute objects and destroys them. To trigger this issue, an attacker may create a malicious web page and persuade a user to view it. Successful exploitation of this vulnerability will allow an attacker to take complete control of the affected system.
