Apple on Tuesday released QuickTime 7.6.6 to resolve 12 vulnerabilities, all of which could lead to arbitrary code execution. In most cases, the vulnerabilities could be exploited if a user is tricked into viewing a malicious movie file. Eleven of the flaws impact Mac OS X, Windows 7, Vista and XP Service Pack 2. The other does not impact Macs. Also on Tuesday, Apple distributed iTunes 9.1 to close off seven holes. — DK
