What is CVE-2018-3993?

An exploitable use-after-free vulnerability exists in the JavaScript engine of Foxit PDF Reader, specifically in version 9.2.0.9297. When a specially crafted PDF document is opened, it can trigger the reuse of a previously freed object in memory, which may allow an attacker to execute arbitrary code on the targeted system. To exploit this vulnerability, an attacker must entice the user into opening the malicious PDF file.
