Adobe has provided a Flash Player 9 update to resolve vulnerabilities in Flash Player. These vulnerabilities would allow remote attackers to modify HTTP headers of client requests and conduct HTTP Request Splitting attacks. Adobe Flash Player 9.x, 8.x, and 7.x. The custom-header addition feature was added starting with Adobe Flash Player 7, thus Flash Player 6 and earlier are not affected.

Adobe recommends all users of Adobe Flash Player 9.0.20.0 and earlier versions upgrade to the newest version 9.0.28.0, by downloading it from the Player Download Center, or by using the auto-update mechanism within the product when prompted.
