Mozilla patches critical flaws

February 20, 2010 Leave a comment Go to comments

Mozilla has released fixes for five security holes in older versions of Firefox, while a security company has warn of a zero-day flaw in the latest version of the well-liked browser.

Mozilla issued patches Wednesday for versions 3.5.8 and 3.0.18 of the browser, sending out fixes for the latter even though it had said it would stop supporting Firefox 3.0 in January. In its security bulletin, the company said the vulnerabilities had previously been resolved in Firefox 3.6, which was launched on January 21. The five flaw addressed by Mozilla included three the company rated “critical.” Those three flaws involve a mistake in handling out-of-memory conditions; stability errors in the Gecko rendering engine; and a bug in the way Mozilla’s implementation of Web Worker handle posted messages.

Separately, Secunia reported Thursday an unpatched bug in Firefox 3.6, the most new version of the browser. The security firm warned that the software contain a bug that could be used to carry out malicious code on a user’s system.
