Foxit Reader is a PDF reader that is available on multiple operating systems.

From the Secuia Research advisory Foxit Reader "util.printf()" Buffer Overflow:
Secunia Research has discovered a vulnerability in Foxit Reader, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error when parsing format strings containing a floating point specifier in the "util.printf()" JavaScript function. This can be exploited to cause a stack-based buffer overflow via a specially crafted PDF file.

To exploit this vulnerability an attacker would have to persuade a user to open a specially crafted PDF file. The malicious PDF could be hosted on a web page or sent via email.

A remote, unauthenticated attacker may be able to execute arbitrary code.

Foxit Reader version 2.3 build 2912 was released to address this issue.
