Apple issued QuickTime 7.7 for Windows and Mac OS X Leopard, as well as a batch of driver updates for printers and scanners from Samsung, HP and Brother.
HP Printer Drivers v.2.7 for Mac OS X v10.6
Samsung Printer Drivers v2.2 for Mac OS X v10.6
Brother 2.7 Printer Drivers for Mac OS X v10.6
Beside driver updates, Apple has issued an update for QuickTime in OS X Leopard, which brings the version to 7.7. This update requires OS X 10.5 or later and is a ~69MB download through Software Update. Unfortunately while Apple’s support downloads site lists the update, the linked downloads pages for the new software points to the older 7.6.9 update so we cannot yet link to it from here. Apple’s security updates page mentions that the update mainly is for security to prevent the execution of arbitrary code in specific situations when handling media with the QuickTime program.
