that Adobe Acrobat, Reader, and Flash Player are prone to a remote code-execution vulnerability. An attacker can exploit this issue by supplying a malicious Flash ('.swf') file or by embedding a malicious Flash application in a PDF file. Successful exploits may allow the attacker flash 10.0.22to execute arbitrary code in the context of the user running the affected application. Failed attempts will likely result in denial-of-service conditions. The issue affects the following: Reader and Acrobat 9.1.2 Flash Player 9 and 10 and indicated that version Adobe Flash Player 10.0.22.87 is vulnerable. But how woudl I know that I needed to update? this came out 7/21/09 and I never reflash 10.0.22ceived any prompt from my version of flash player that I needed to update
just google and get the new flash player also this exploit you could get only if you click on a link that had came into email or you go to a site that is craftet but if you u have a firewall and an antivirus then you are 90% protected so don't worry to much.
