Apple's description of the update mentions disabling QT's Flash media handler: "Description: Multiple vulnerabilities exist in QuickTime's Flash media handler, the most serious of which may lead to arbitrary code execution. With this update, the Flash media handler in QuickTime is disabled except for a limited number of existing QuickTime movies that are known to be safe." Since I view a lot of Flash based content (YouTube type stuff), which I often download using Perian, I've hesitated to install this update. Does anyone have any feedback on what effect the update has on YouTube type material?
