**Name of the Vulnerable Software and Affected Versions** Mozilla Firefox versions prior to 41.0 **Description** The issue is related to errors in the JavaScript implementation code in Mozilla Firefox. When the Debugger API is enabled, a remote attacker can exploit this to cause a denial of service or possibly execute arbitrary code via a crafted web site. The SavedStacks class is specifically affected, leading to a getSlotRef assertion failure and application exit. **Recommendations** For versions prior to 41.0, update to version 41.0 or later to resolve the issue. As a temporary workaround, consider disabling the Debugger API until a patch is available.
