Apple patched 15 vulnerabilities in its QuickTime media player for Windows and Mac OS X 10.5, aka Leopard. The company had patched nine of the bugs in Snow Leopard's version of QuickTime almost a month ago when it updated that edition of Mac OS X to 10.6.5 with a massive 134 fixes. Two of the 15 affected only QuickTime for Windows; the remaining 13 patched both Leopard's and Windows' QuickTime 7.6.9.
All but one of the 15 were rated "critical" by Apple , which used its usual "May lead to arbitrary code execution" phrase rather than an explicit ranking. Unlike other major developers, such as Google, Microsoft and Oracle, Apple doesn't assign threat levels to the vulnerabilities it patches.
QuickTime 7.6.9 can be downloaded from Apple's site for Mac OS X, Windows XP, Windows Vista and Windows 7. Mac users can upgrade to QuickTime 7.6.9 using the operating system's built-in Software Update feature, while Windows users can either download the new edition from the Apple site or use the optional Windows update tool.
