This is going to have an impact on confidentiality, integrity, and availability.

The issue has been introduced in 06/26/2013. The weakness was released 03/14/2014 by Abdul Aziz Hariri with Zero Day Initiative (ZDI) as Pwn2Own results for Thursday (Day Two) as not defined blog post (pwn2own). The advisory is available at pwn2own.com. The blog post contains:

The second and final day of Pwn2Own 2014 saw successful attempts by seven entrants against five products, with $450,000 paid to researchers. This brings the two-day payout total to $850,000, not including charitable donations or the value of the laptops, ZDI points, and other prizes given to winning researchers.
It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Successful exploitation requires user interaction by the victim. Technical details are unknown but an exploit is available. The structure of the vulnerability defines a possible price range of USD $25k-$100k at the moment (estimation calculated on 04/07/2017). It is expected to see the exploit prices for this product decreasing in the near future.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 261 days. During that time the estimated underground price was around $25k-$100k.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at X-Force (92680) and SecurityFocus (BID 63728†). Entries connected to this vulnerability are available at VDB-12721, VDB-13024, VDB-13025 and VDB-13027. If you want to get best quality of vulnerability data, you may have to visit VulDB.
