Apple has released a new version of its QuickTime media player, version 7.6.7. This release is, apparently, for Windows only (XP, Vista, or 7) at this time. Apple says that the update “improves security and is recommended for all QuickTime 7 users on Windows”. This update addresses a specific security vulnerability (CVE-2010-1799); further information is available in Apple’s Security Bulletin. (The vulnerability does not affect Mac OS X, according to Apple.) The updated version is available via Software Update, or can be downloaded here.
