What is CVE-2018-3992?

A use-after-free vulnerability found in the JavaScript engine of Foxit Software's Foxit PDF Reader allows a specially crafted PDF document to exploit memory management flaws. When a previously freed object is accessed again, it can lead to arbitrary code execution. Attackers can trigger this vulnerability by convincing users to open a maliciously crafted PDF file. Additionally, if the browser plugin extension is active, simply visiting a compromised website could also exploit this vulnerability.
