This Wednesday Apple has released new QuickTime update on all platforms addressing flaws occurring when the application opens a movie that has been specially crafted to take advantage of flaws in the software. Several of the vulnerabilities are buffer overflows, where a problem with an application’s use of memory can be exploited in order to run other code. Latest up to date version QuickTime is now 7.4.5 and Apple’s Software Update function will download the new patches for computers running Windows and Apple’s Mac OS X.
