Apple has released a new version, 7.6.8, of its QuickTime media player. This update applies only to the Windows platform, and contains fixes for two serious security vulnerabilities. More information about the fixes is available in Apple’s security advisory. You can get the new version using Apple’s software update service, often installed with QuickTime, or you can download it here.
The QuickTime player is widely installed, both as a stand-alone application, and as a browser plug-in. Because of the security content of this release, I recommend that Windows users install it as soon as they can.
