The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to insufficient validation of user-supplied input within the JavaScriptCore component in WebKit. A remote attacker can trick the victim into visiting a specially crafted web page and execute arbitrary code on the system.

Note, the vulnerability is being actively exploited in the wild against Intel-based Mac systems.
