With the release of Flash Player 10, Adobe fixes a critical security vulnerability known as "clickjacking." But for those users who can't or don't want to update to the latest version -- well, they're out of luck for a while.Adobe Systems' latest Flash Player 10 software, released yesterday, fixes a number of security flaws, including the recently famous clickjacking attack, according to this Adobe blog post. But if you run into problems installing 10, you'll have to sit tight -- and remain vulnerable -- for a few more weeks.

Here's how InformationWeek's Thomas Claburn summed things up a week ago, regarding the clickjacking threat:

Details about the cross-platform browser exploitation technique known as "clickjacking" have started to emerge. Among the more alarming ways it can be used: covertly watching and listening to people who have microphones and Webcams attached to their computers.

"Web pages know what Web sites you've been to, ... where you're logged in, what you watch on YouTube, and now they can literally 'see' and 'hear' you," warned Jeremiah Grossman, founder and CTO of WhiteHat Security, in a blog post.

On Tuesday, Flash developer Guy Aharonovsky published a proof-of-concept exploit to show how clickjacking can be used to spy on people. "I've written a quick and dirty JavaScript game [to] exploit just that, and demonstrate how an attacker can get a hold of the user's camera and microphone," he said in a blog post. "This can be used, for example, with platforms [like Ustream.tv or Justin.tv] or to stream to a private server to create a malicious surveillance platform."

Grossman and Robert "RSnake" Hansen, founder and CEO of SecTheory, discovered the clickjacking technique, called "UI redressing" by some, and planned to discuss it at the 2008 Open Web Application Security Project USA NYC security conference last month. But the pair decided to delay disclosure to allow affected vendors time to address the issue.

It's important to note that clickjacking isn't specific to Adobe products, but they're widely used. Here's the link to Adobe's security bulletin.
