Description
An exploitable use-after-free vulnerability exists in the JavaScript engine of Foxit Software Foxit PDF Reader version 9.0.1.1049. A specially crafted PDF document can trigger a previously freed object in memory to be reused resulting in arbitrary code execution. An attacker needs to trick the user to open the malicious file to trigger this vulnerability. If the browser plugin extension is enabled, visiting a malicious site can also trigger the vulnerability.
