Hackers are embedding malicious Flash Player files in Microsoft Word documents to launch targeted attacks against select businesses, according to a warning from Adobe.

This latest Flash Player zero-day attack comes just weeks after EMC's RSA Division was hit with a malware attack that used a rigged Flash (.swf) file embedded in a Microsoft Excel document.

In both cases, the attacks are being used to steal corporate secrets.

Here's the gist of the latest Flash Player zero-day:

A critical vulnerability exists in Flash Player 10.2.153.1 and earlier versions (Adobe Flash Player 10.2.154.25 and earlier for Chrome users) for Windows, Macintosh, Linux and Solaris, Adobe Flash Player 10.2.156.12 and earlier versions for Android, and the Authplay.dll component that ships with Adobe Reader and Acrobat X (10.0.2) and earlier 10.x and 9.x versions for Windows and Macintosh operating systems.

This vulnerability (CVE-2011-0611) could cause a crash and potentially allow an attacker to take control of the affected system. There are reports that this vulnerability is being exploited in the wild in targeted attacks via a Flash (.swf) file embedded in a Microsoft Word (.doc) file delivered as an email attachment, targeting the Windows platform. At this time, Adobe is not aware of any attacks via PDF targeting Adobe Reader and Acrobat. Adobe Reader X Protected Mode mitigations would prevent an exploit of this kind from executing.

Adobe says it is in the process of finalizing a schedule for delivering patches for Flash Player 10.2.x and earlier versions for Windows, Macintosh, Linux, Solaris and Android, Adobe Acrobat X (10.0.2) and earlier 10.x and 9.x versions for Windows and Macintosh, Adobe Reader X (10.0.2) for Macintosh, and Adobe Reader 9.4.3 and earlier 9.x versions for Windows and Macintosh.

Because Adobe Reader X Protected Mode would prevent an exploit of this kind from executing, Adobe plans to fix this issue in Adobe Reader X for Windows with the next quarterly security update for Adobe Reader, currently scheduled for June 14, 2011.
