Gaping Holes In Fully Patched IE7, Firefox 2 303
Continent1106 writes "Hacker Michal Zalewski has ratcheted up his ongoing assault on Web browser security models, releasing details on serious flaws in fully patched versions of IE6, IE7 and Firefox 2.0. The vulnerabilities could cause cookie stealing, page hijacking, memory corruption, code execution, and URL bar spoofing attacks." Here is Zalewski's post to Full Disclosure.

IMHO, this must be something related to running Windows, as my Kubuntu 7.04 Feisty w/ Firefox 2.0.04 (with NoScript, Adblock, Adblock Filterset, and Flashblock) just does not act on this.
I guess I need to install some version of Windows to experience this...I feel deprived and left out!
Does this work with Firefox w/ NoScript on Windows?
From past experience, I have no doubts that it works with any version of IE on any Windows platform.

You can also install Firefox and use one of the IE-look-alike themes.

You can also set IE Tabs and have it open IE-only sites on an IE tab by default, this requires nothing more than two mouse clicks.

I think it's a shame though; the old tagging system added a good bit of fun to the site, and the "joke" tags were sometimes very appropriate indeed.

The old system was better because it provided a snapshot of what people thought about the story, despite being much more open to abuse.

I run a few perfectly un-shady sites (an imageboard, a specialized search engine, and a funny images repository), but recently some users started complaining about the popups that were trying to install spyware.
I don't have any popups on my sites! (I don't even use target="_new"!) but still users were getting spyware popups. The popups were so evil that the only way to avoid getting redirected to the spyware site was to disable javascript (Even in firefox. in IE it just installed the spyware automatically, but firefox at least you had to click "download". Still, it made my site unusable)
I went into my advertisers control panel, checked for anything remotely shady. Nothing. I tried turning off all third party advertisers (like doubleclick), figuring maybe one of them was redirecting users. Nope, some users still got popups. Worst of all, I NEVER got the popup, no matter what browser I was using.
It turns out it's cause I'm an American. The advertiser had specified that the advert with the embedded redirect only show up in every country except America. That stopped me from seeing it on the site, but what about the control panel? I could see all the ads there, even the ones not targeted at my location. Here's what they did in actionscript: (pseudocode)
So even when I checked the ads in the control panel they looked fine.
My point is, don't think there's a scary corner of the internet where all the spyware/exploits hang out. The bastards making this crap know that most people don't go to those kinds of places, so they'll do anything they can to sneak their crap onto legitimate sites.
