Mozilla Firefox < 29.0 Multiple Vulnerabilities

high Nessus Network Monitor Plugin ID 8213
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote host has a web browser installed that is vulnerable to multiple attack vectors.


Versions of Mozilla Firefox earlier than 29.0 are unpatched against the following vulnerabilities :

- Use-after-free vulnerabilities in nsHostResolver, imgLoader, and Text Track Manager (for HTML video), which can crash with a potentially exploitable condition (CVE-2014-1532, CVE-2014-1531, CVE-2014-1525)
- A potentially exploitable out-of-bounds write in Cairo, a potentially exploitable out-of-bounds read issue with Web Audio, and a non-exploitable out-of-bounds read when decoding JPG images (CVE-2014-1528, CVE-2014-1522, CVE-2014-1523)
- Improper wildcard matching of domains in the Network Security Services (NSS library), which has since been fixed by updating to version 3.16 (CVE-2014-1492)
- Potential privilege escalation via Xray Wrappers bypass, which can occur if a user used the debugger to interact with a malicious page (CVE-2014-1526)
- Privilege escalation for scripts when sites that have been granted notification permissions by a user can bypass security checks on source components for the Web Notification API (CVE-2014-1529)
- Privilege escalation via the Mozilla Maintenance Service Installer, which writes to a globally writeable temporary directory during the update process (Windows only) (CVE-2014-1520)
- A potentially exploitable buffer overflow when a script uses a non-XBL object as an XBL object (CVE-2014-1524)
- A cross-site scripting vulnerability using browser navigations through history to load a website with the page's base URI pointing to a different site (CVE-2014-1530)
- Various memory safety hazards (CVE-2014-1518, CVE-2014-1519)


Upgrade to Firefox 29.0, or later.
