**Name of the Vulnerable Software and Affected Versions** Mozilla Firefox versions prior to 47.0 **Description** The issue exists due to the browser's failure to properly enforce web page structure protection, allowing a remote attacker to conduct cross-site scripting (XSS) attacks using a specially crafted applet. This can be achieved by ignoring Content Security Policy (CSP) directives for cross-domain Java applets. **Recommendations** For versions prior to 47.0, update to version 47.0 or later to resolve the issue. As a temporary workaround, consider disabling the use of Java applets in Mozilla Firefox until a patch is applied. Restrict access to potentially vulnerable web pages to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** Mozilla Firefox versions prior to 22.0 **Description** The issue concerns the getUserMedia permission implementation, which incorrectly references the URL of a top-level document instead of the URL of a specific page. This makes it easier for remote attackers to trick users into permitting camera or microphone access via a crafted web site that uses IFRAME elements. **Recommendations** For versions prior to 22.0, update to version 22.0 or later to resolve the issue.

For Firefox ESR 17.x versions prior to 17.0.6, update to version 17.0.6 or later. For Thunderbird versions prior to 17.0.6, update to version 17.0.6 or later.
