Description

A type confusion vulnerability exists in the way Foxit Reader 12.1.2.15356 handles field value properties. A specially crafted Javascript code inside a malicious PDF document can trigger this vulnerability, which can lead to memory corruption and result in arbitrary code execution. An attacker needs to trick the user into opening the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially crafted, malicious site if the browser plugin extension is enabled.
