Another Zero-Day IE Scripting Exploit

billstewart writes "A Computerworld Article reports a pair of vulnerabilities to Internet Explorer that allow Windows machines to be 0wned by a single click on a malicious web page. It was discovered by Dutch researcher Jelmer. As usual, the primary workaround is to disable Active Scripting for any sites that aren't Trusted, but you should have turned off that and Javascript years ago for safety anyway. At least one of the holes is fixed in XP Service Pack 2, but that doesn't fix previous versions of Windows and it's still only beta."

    No, javascript is not essential. All my normal browsing is done with no javascript, flash or cookies, filtered through privoxy (to get rid of ad junk).

(But sometimes I just look at the source to figure out the links and cut/paste them to go there anyway.)

    There are a few exceptions; sites that need javascript that I really do want to use. For these, I fire up another browser just for the purpose of entering that site. And close that browser when I'm done.

    If you design sites with a wide audience, you may want to ensure that anyone can use the site, from any browser using basic technology (HTML).
