**Name of the Vulnerable Software and Affected Versions** Mozilla Firefox versions prior to 42.0 **Description** The issue is related to improper interaction between the accessibility-tools feature and the implementation of the TABLE element, allowing remote attackers to cause a denial of service or possibly execute arbitrary code by using an `NSAccessibilityIndexAttribute` value to reference a row index. This can be achieved by exploiting errors in the code, potentially enabling a remote attacker to crash the application or execute arbitrary code. **Recommendations** For versions prior to 42.0, update to version 42.0 or later to resolve the issue.
