Apple has released a series of security updates to address 77 CVE-listed security vulnerabilities in OS X Yosemite.
The Yosemite 10.10.4 update includes fixes for QuickTime, OpenSSL and ImageIO, along with remote code execution flaws and other exploits that could allow an attacker to obtain elevated privileges or crash applications.
The Safari update includes fixes for four vulnerabilities in the WebKit browser engine. An attacker could target the flaws to remotely execute code, steal account information, view WebSQL databases and lift cookie information from a targeted Mac.
Users running Yosemite should update their system software to install the security fixes as soon as possible. Those running older versions of OS X can get some of the updates by installing patches for Safari 6, 7 and 8.
Users running iOS devices should also receive an update to address 32 CVE-listed vulnerabilities in WebKit and other components of the mobile platform. Five of the flaws were in WebKit, additional patches included the iOS Kernel, ImageIO, and Mail.
In addition to the security updates, the iOS 8.4 release will give iOS users access to Apple Music, the streaming service Tim Cook unveiled earlier this month at WWDC. Apple is offering a free three-month trial of the service, after which users will be billed $9.99 per month.
The iOS update also revokes dodgy security certificates issued by CNNIC.
OS X users can download the update through the Software Update tool. iOS devices can get the update through the "general" control in the OS X Settings app. ®
