Added Description

Foxit PDF Reader print Method Use of Externally-Controlled Format String Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Foxit PDF Reader. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the implementation of the print method. The issue results from the lack of proper validation of a user-supplied string before using it as a format specifier. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. Was ZDI-CAN-14849.
