Apple releases security updates: Alert Priority High

20 July 2017

Apple releases security updates for multiple products.

Apple released security updates to address vulnerabilities in a number of their products including Apple TV, iTunes, iCloud, Safari, macOS, iOS and Apple Watch. If these updates haven’t been installed automatically on your Apple devices already, or if you postponed the installation when prompted, install them now.

What to do now

Install the latest updates for your Apple products if you haven’t already. You can learn more about these updates using these links:

All security updates for Apple products are also listed here.


Security updates fix vulnerabilities in computer systems that attackers may use to gain unauthorised access or to perform other malicious activity.

A vulnerability is a weakness that can be exploited by attackers to compromise or otherwise adversely affect a computer system. It is usually an unintended consequence of design or configuration.

Typically attackers exploit vulnerabilities in order to perform other malicious actions, such as stealing or corrupting information, installing malware or stopping the affected system from working correctly.

Staying safe

Stay Smart Online recommends, whenever possible, choosing to automatically apply security updates when they become available. Automatic updates minimise the risk of delaying or forgetting to apply an update, and limit the chance that attackers will gain access to your computer and sensitive personal and financial data.

If you choose not to install updates automatically, you should review the information provided to see if any products you use are affected. If they are affected install the updates as soon as possible to minimise the risk of being attacked.
