Upon successful exploitation, it will drop two DLLs. The first DLL shows a fake error message and opens a decoy PDF document, which is usually common in targeted attacks. The second DLL in turn drops the callback component, which talks to a remote domain.
We have already submitted the sample to the Adobe security team. Before we get confirmation from Adobe and a mitigation plan is available, we suggest that you not open any unknown PDF files. We will continue our research and continue to share more information.

These vulnerabilities could cause the application to crash and potentially allow an attacker to take control of the affected system.
Adobe is aware of reports that these vulnerabilities are being exploited in the wild in targeted attacks designed to trick Windows users into clicking on a malicious PDF file delivered in an email message.
Adobe is in the process of working on a fix for these issues and will update this advisory when a date for the fix has been determined.
