Firefox Won’t Save You from IE Flaws

Users running Firefox are vulnerable to IE flaws via files supported by Windows Media Player, a researcher shows.
Running Firefox or Opera as a default browser won’t save you from unpatched Internet Explorer vulnerabilities—a fact made explicit when a researcher showed how easy it is to put HTML inside files supported by Windows Media Player.
Researcher Petko D. Petkov said in a Sept. 18 blog posting that he’s found that a fully patched Windows XP Service Pack 2 system running Internet Explorer 6 or 7 along with Windows Media Player 9—the default, although the media player is now up to Version 11—will open any page of an attacker’s choice even if the default browser is not Internet Explorer.
Adblock effectively robs these free sites of their revenue. If Internet Explorer came with a feature such as Adblock, it would effectively wipe out thousands of websites, maybe more. These are the same free sites users of Adblock frequently visit. The irony is how this is self-defeating.
