An exploitable use of an uninitialized pointer vulnerability exists in the JavaScript engine in Foxit PDF Reader version

An exploitable use of an uninitialized pointer vulnerability exists in the JavaScript engine in Foxit PDF Reader version 9.0.1.1049. A specially crafted PDF document can lead to a dereference of an uninitialized pointer which, if under attacker control, can result in arbitrary code execution. An attacker needs to trick the user to open a malicious file to trigger this vulnerability.

If the browser plugin extension is enabled, visiting a malicious site can also trigger the vulnerability.
