Firefox 3.5 JS security vulnerability emerges

updated 12:40 am EDT, Wed July 15, 2009

Firefox security issue

A new security vulnerability affecting Firefox 3.5 has been discovered, according to Secunia. The issue, spotted by Simon Berry-Byrne, relates to an error when processing JavaScript code, such as "font" HTML tags, and can be exploited to cause memory corruption. The flaw potentially could be used to allow malicious code to enable unauthorized control of a system.

The vulnerability is unpatched with the latest versions of Firefox. Until Mozilla addresses the issue, Secunia recommends that users avoid navigating to untrusted websites or following untrusted links.

    NoScript FTW

    Use NoScript to selectively enable Javascript for sites you trust.

    I love these solutions. Its like also saying "Once we fix this bug, you can go back and surf all those untrusted and unknown websites everyone loves surfing to."
