Together, <A HREF="http://www.webware.com/8301-1_109-9741435-2.html?tag=nl.e501">Firefox and Internet Explorer are brewing up some security trouble.</A> That's the latest update from security researchers who initially laid the blame on Microsoft's Internet Explorer for the latest zero-day exploit that also can afflict those using the Firefox Web browser.
Users could face a "highly critical" risk if they have both IE and Firefox version 2.0, or later, loaded on their computer. The trouble begins when browsing a malicious site while using IE and it registers a "firefoxurl://" URI (uniform resource identifier) handler, which allows the browser to interact with specific resources on the Web. As a result, users may find their systems remotely compromised.
Earlier Tuesday, security researcher Thor Larholm, who discovered the IE flaw, and security research giant Symantec put much of the blame on IE, while Secunia's Thomas Kristensen, chief technology officer, attributed the problem to Firefox versions 2.0 or later.
