Adobe on Thursday released an update to its Flash Player software that fixes at least 18 security vulnerabilities. The update is available for Windows, Macintosh, Linux, and Solaris versions of Flash. If you use Internet Explorer in addition to other browsers, you will need to apply this update twice: Once to install the Flash Active X plugin for IE, and again to update other browsers such as Firefox or Google Chrome with this fix. Adobe recommends that users uninstall the previous version of Flash before updating to the latest copy.”]
