Apple has issued security updates for Mac OS 10.5 (Leopard) and Mac OS 10.6 (Snow Leopard), as well as additional performance and stability updates for Snow Leopard.
The v10.6.3 update fixes compatibility issues with components such as QuickTime, Open GL and DNS, and stabilises USB drive and printing reliability.
The Snow Leopard update also improves the performance of LogicPro 9, Bonjour, iMovie and iChat, according to Apple.
The security update includes 69 fixes for various components in Leopard and Snow Leopard, including nine vulnerabilities in QuickTime and four in the ImageIO component.
The patches are part of the 10.6.3 update for Snow Leopard, but the download will be a standalone security update for Leopard users.
The Safari vulnerabilities exploited by researcher Charlie Miller at last week's CanSecWest Pwn2Own competition are not mentioned in Apple's security release.
The company did, however, credit multiple vulnerability disclosures in the update to known and anonymous researchers working for Pwn2Own contest host TippingPoint.
