Summary

A use-after-free vulnerability in the JavaScript engine of Foxit PDF Reader allows for potential arbitrary code execution. The flaw is triggered when objects associated with PDF pages are prematurely deleted, enabling a specially crafted PDF document to reuse memory that has already been freed. This can occur when a user is deceived into opening a malicious PDF file or visiting a compromised website while the browser plugin extension for Foxit is enabled. Ensuring software is up-to-date and exercising caution with unsolicited documents are crucial steps to mitigate the risk.
