**Name of the Vulnerable Software and Affected Versions** Mozilla Firefox versions prior to 43.0 **Description** The issue is related to errors in storing the properties of unboxed objects, which can be exploited by remote attackers to execute arbitrary code via crafted JavaScript variable assignments. This can be achieved through specially formed JavaScript variables. **Recommendations** For versions prior to 43.0, update to version 43.0 or later to resolve the issue. As a temporary workaround, consider restricting the execution of JavaScript code from untrusted sources until the update is applied.
