Mozilla Firefox < 3.6.24 Multiple Vulnerabilities

high Nessus Network Monitor Plugin ID 9377
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.

Synopsis

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

Description

Versions of Firefox earlier than 3.6.24 are potentially affected by multiple vulnerabilities :

- A flaw exists within the 'JSSubScriptLoader' that incorrectly unwraps 'XPCNativeWrappers'. By tricking a user into installing a malicious plug-in, an attacker could exploit this issue to execute arbitrary code. (CVE-2011-3647)
- Certain invalid sequences are not handled properly in 'Shift-JIS' encoding and can allow cross-site scripting (XSS) attacks. (CVE-2011-3648)
- Profiling JavaScript files with many functions can cause the application to crash. It may be possible to trigger this behavior even when the debugging APIs are not being used. (CVE-2011-3650)

Solution

Upgrade to Firefox 3.6.24 or later.
