Mozilla released two new versions of its browser on Tuesday, Firefox 3.6.9 and Firefox 3.5.12, to close 10 critical security vulnerabilities in each and to help Web site operators block a risk called clickjacking. Firefox 3.6.9 is also available from CNET Download.com for Windows, Mac, and Linux. Critical vulnerabilities can let a remote attacker run arbitrary code on a computer. With Web browsers becoming both more important and more powerful, browser makers must constantly watch for new attack possibilities. Firefox 3.6 also gets a new general approach to cut down browsing risks: support for what's called the X-Frame-Options HTTP response header. Web site developers can use this technology to block browsers from showing their Web sites inside a frame--essentially a smaller window within the browser window. Putting a legitimate site inside a frame on a malicious site is one approach for attacks called clickjacking, in which the malicious site can capture keystrokes such as usernames and passwords.

Firefox 3.6.9 now supports the X-FRAME-OPTIONS header, which enables web servers to forbid clients from opening downloaded pages in iframes. Clickjacking involves an attacker website inserting a transparent iframe containing, for example, Facebook content under the cursor. Users think they are clicking on the visible web page, but are in fact clicking on elements in the transparent Facebook iframe.. Earlier this year, hundreds of thousands of Facebook users fell victim to a clickjacking attack after unwittingly clicking on a concealed 'Like' button on a crafted web page. The new option would allow Facebook to prevent attackers from loading content in an iframe in Firefox. Despite the fact that Internet Explorer 8 and Chrome already support this option, Facebook is not using it. The link for this article located at H Security is no longer available. .

Read on for info on this new security vulnerability, and learn exactly how it works. Lots of people seem to have an opinion on this article at CNET. Do you see this vulnerability as being a big problem for you? "Most exploits (like worms and attacks that take advantage of holes in software) can be patched, but clickjacking is a design flaw in the way the Web is supposed to work," Grossman said. "The bad guy is superimposing an invisible button over something the user wants to click on...It can be any button on any Web page on any Web site." The technique was used in a series of prank attacks launched on Twitter in February. In that case, users clicked on links next to tweets that said "Don't Click" and then clicked on a button that said "Don't Click" on a separate Web page. That second click distributed the original tweet to all of the Twitter user's followers, thus propagating itself rather quickly. . At the time, Grossman called it a "harmless experiment," but the potential for harm by an attacker who isn't just having fun is huge. In a demo at CNET offices on Thursday, Grossman showed how someone could launch a clickjacking attack using Flash to spy on someone by getting them to turn on their computer Web cam without knowing it. (Grossman also appeared on CNET Live to talk about clickjacking.) The link for this article located at CNET is no longer available. .
