Apple has released a security update for its QuickTime media framework for Windows. Version 7.7.4 of the software closes 12 critical security holes causing memory corruption and buffer overflows when processing a number of media formats. The vulnerabilities affect Windows 7, Vista and XP SP2 or later and could be exploited to cause arbitrary code execution and application crashes.
The vulnerabilities affected the playback of MP3, H.263, H.264, TeXML, JPEG, QTIF, Sorenson Video and FPX files as well as the handling of dref, enof and mvhd atoms within the program. All of the problems were reported by researchers working with HP’s Zero Day Initiative, five of them by Tom Gallagher and Paul Bates from Microsoft.
At the time of writing, Apple is not yet listing details about the fixed bugs on its security web site, but has announced that it will do so soon. The 40MB update for the free product can be downloaded from Apple’s Support Downloads web site.
