Out of Band Adobe Flash Player Critical Security Update

Out of Band Adobe Flash Player Critical Security Update

Adobe has released security updates for Adobe Flash Player 16.0.0.257 and earlier versions for Windows and Macintosh and Adobe Flash Player 11.2.202.425 and earlier versions for Linux.

Correction: From Threatpost, Adobe Patches One Zero Day in Flash, Still Investigating Separate Vulnerability:

"The vulnerability that Adobe patched Thursday is under active attack, but Adobe officials said that this flaw is not the one that security researcher Kafeine said Wednesday was being used in the Angler attacks."

The Threatpost article further indicated that there is no indication from Adobe officials that an update is in the works for the Angler zero-day vulnerability.



This update address a Zero-Day in Adobe Flash Player discovered by security researcher Kafeine that was being distributed through the Angler Exploit Kit (See Unpatched Vulnerability (0day) in Flash Player is being exploited by Angler EK | Malware dont need Coffee.)  

The update below has been released by Adobe to address the vulnerability.  It is strongly advised that the update be applied as soon as possible.

Flash Player Update Instructions

Warning:  Although Adobe suggests downloading the update from the Adobe Flash Player Download Center, that link includes a pre-checked option to install unnecessary extras, such as McAfee Scan Plus or Google Drive.  If you use the download center, uncheck any unnecessary extras.

It is recommended that you either use the auto-update mechanism within the product when prompted, or my preference, the direct download links.
