OS X 10.8.5 and Security Update 2013-003 -- the latter targets OS X Snow Leopard and OS X Lion, which at this point receive only security fixes -- can be retrieved by selecting "Software Update..." from the Apple menu, or by opening the Mac App Store application and clicking the Update icon at the top right. The updates can also be downloaded manually from Apple's support site.
Apple has not yet revealed a release date for OS X Mavericks, the successor to Mountain Lion, but it will probably ship in the second half of next month.
