Apple today released updates to QuickTime 7.4.5, iTunes 7.6.2, and Front Row 2.1.3, offering several performance enhancements, as well as a patch for a security hole found in QuickTime. The patch fixes an issue related to the SHA-1 checksum, which is related to protecting files with 160-bit encryption. iTunes 7.6.2 doesn't list specifically which issues are fixed, but more than likely resolves compatibility with the new QuickTime version. Front Row's update similarly guarantees functionality with iTunes 7.6.2.
