Adobe has released a patch for a critical Flash Player problem that could let attackers take over people's computers through content viewed in a browser.
The vulnerability affected a file that shipped with Flash Player 9.x and 10.x for Windows, Mac OS X, and Linux, and with Adobe Reader and Adobe Acrobat 9.x for Windows, Macintosh, and Unix. Adobe said Thursday it fixed the problem in a security advisory, and Adobe's Matt Rozen posted a note on Twitter that directed people to download the patched version from Adobe's Flash download site.
This was no abstract, theoretical vulnerability, either.
"There are reports that this vulnerability is being actively exploited in the wild via limited, targeted attacks against Adobe Reader v9 on Windows," Adobe said in an earlier advisory about the problem.
Flash is very widely used in browsers to power features such as interactive stock charts and YouTube video streaming.
