Adobe released a security advisory revealing that a “critical vulnerability” was found in pretty much all versions of the multimedia platform as well as in Adobe Acrobat and Adobe Reader.
Affected versions include: “Adobe Flash Player 10.2.152.33 and earlier versions (Adobe Flash Player 10.2.154.18 and earlier for Chrome users) for Windows, Macintosh, Linux and Solaris operating systems, Adobe Flash Player 10.1.106.16 and earlier versions for Android, and the Authplay.dll component that ships with Adobe Reader and Acrobat X (10.0.1) and earlier 10.x and 9.x versions of Reader and Acrobat for Windows and Macintosh operating systems.”
The vulnerability could result in a crash or potentially be exploited by a hacker to “take control of the affected system.” Worse, there are reports already that this security hole is being exploited via a Flash file (.swf) embedded in a Microsoft Excel (.xls) spreadsheet that arrives as an e-mail attachment.
Work on a fix is underway. Those versions of software with critical flaws — which is everything other than Reader X, are getting the most attention. Adobe expects a fix to go live “during the week of March 21, 2011.”
