The Mozilla Foundation has released a patch for a critical security hole in its open source Firefox browser.

The Mozilla Foundation has released a patch for a critical security hole in its open source Firefox browser.

The bug could be used by remote attackers to crash the browser or install their own malicious code on users’ machines.

The Firefox 1.5.0.3 update fixes the vulnerability, which was found in Firefox 1.5.0.2 – itself only issued in mid-April.

Security researchers said that malformed JavaScript code could use the bug to crash the browser.

A number of the 25 bugs fixed in the release of Firefox 1.5.0.2 are related to JavaScript vulnerabilities, and the problem in browsers in general is not uncommon.

Firefox now has around 10% of the browser market and is number two behind Microsoft’s Internet Explorer.
