On April 15, 2011 Adobe released a Security advisory called Security update available for Adobe Flash Player that announced the availability of an update to their Flash Player 10 software.
Note: There are reports that this vulnerability is being exploited in the wild in targeted attacks via a malicious Web page, or a Flash (.swf) file embedded in a Microsoft Word (.doc) or Microsoft Excel (.xls) file delivered as an email attachment, targeting the Windows platform. The advisory states in part:
A critical vulnerability has been identified in Adobe 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, and Adobe Flash Player 10.2.156.12 and earlier versions for Android. This vulnerability (CVE-2011-0611), as referenced in Security Advisory APSA11-02, could cause a crash and potentially allow an attacker to take control of the affected system.
Action Required: Ag IT recommends that you update the Adobe Flash Player on your Enterprise machine (or other devices that use Adobe Flash) to mitigate the effects of malicious SWF (Flash) files that you might view in your web browser, Word, or Excel file.
