Adobe delivers emergency fix for Flash, Reader, and Acrobat

22 March 2011

Yesterday Adobe issued a patch for a critical vulnerability affecting Flash Player, Reader, and Acrobat. The flaw had been exploited in the wild via targeted attacks using malicious Flash files embedded in Excel files and attached to emails.

As reported previously by Infosecurity, Adobe announced the emergency patch last week when it made the exploit public. The company said it is not aware of any attacks affecting Reader or Acrobat.

The first security update addresses what Adobe called a “critical” security flaw for Reader and Acrobat that affects the authplay.dll component of both applications. The fix is for Adobe Reader and Acrobat X 10.0.1 and earlier 10.x and 9.x versions for both Windows and Mac.

In a second security bulletin, Adobe has issued a fix for the “critical” security bug affecting its Flash Player. The flaw concerns Adobe Flash Player and earlier versions for Windows, Mac, Linux, and Solaris (Flash Player and earlier for Chrome users), in addition to and earlier versions for the Android mobile OS.

Adobe has recommended immediate updates of all the affected software due to the limited known zero-day exploits.
