Name of the Vulnerable Software and Affected Versions: Foxit PDF Reader (affected versions not specified)

Description: This issue allows remote attackers to disclose sensitive information on affected installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The flaw exists within the implementation of the print method due to 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 issues to execute arbitrary code in the context of the current process.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
