User interaction is required to exploit this vulnerability in that the target must visit a malicious page.
The specific flaw exists in the handling of the run-in value for display CSS styles. A specially crafted web page can cause a use after free() condition in WebKit’s WebCore::RenderBlock() method. This can be further leveraged by attackers to execute arbitrary code under the context of the current user.
Apple has issued an update to correct this vulnerability. More details can be found at:
