   Apple Issues Urgent Security Updates to OS X and Safari

   Josh Centers

   Apple has issued three Mac security updates: [1]Security Update
   2016-001 El Capitan, Security Update 2016-005 Yosemite, and [2]Safari
   9.1.3 for OS X 10.9.5 Mavericks and OS X 10.10.5 Yosemite. All three
   updates are related to the major vulnerabilities discovered in iOS by
   Citizen Lab and Lookout (they're credited in the release notes), as we
   reported in '[3]iOS 9.3.5 Blocks Remote Jailbreak' (25 August 2016).
   Due to the severity of these vulnerabilities, we encourage everyone to
   install these updates as soon as possible.

   You can download the 414.9 MB [4]Security Update 2016-001 and the 468
   MB [5]Security Update 2016-005 directly from Apple's Web site or
   install them via Software Update. Safari 9.1.3 is available only via
   Software Update.
