Home Business IT Open Source Firefox 3.6.9 addresses security issues

The latest release of popular open-source browser Firefox addresses multiple security issues.

The sole new feature in Firefox 3.6.9 is support for the X-FRAME-OPTIONS HTTP response header. This can be used by web sites to help protect visitors from clickjacking attacks by ensuring that content is not embedded into other sites.

Firefox 3.6.9 also delivers fixes for 14 security vulnerabilities, 10 of them rated critical. Issues include the potential to load a malicious copy of dwmapi.dll under Windows XP, and crashes caused my maliciously crafted fonts on Mac OS X.

The update also includes one high impact vulnerability, one moderate, and two low.

Users of Windows and Mac OS X versions of Firefox can most easily update by using the browser's Check for Updates command. Complete installers are available here.
