Mozilla and Apple provide updates to address security flaws

Priority Level: 
High
21 September 2016

Mozilla and Apple have released security updates for software used widely on desktop computers, smartphones, tablets and other systems.

Security updates address vulnerabilities in computer systems that remote attackers can otherwise use to gain access to devices, or information such as online banking details. A vulnerability is a weakness that can leave a computer and its systems open to attack.  Attacks can be carried out a number of ways, including through malicious software (malware) such as viruses and spyware that can monitor a users' activity on a computer and stop systems operating properly.

Stay Smart Online recommends that where technology companies enable you to automatically apply security updates when they become available, you do so.  Information on automating updates is available here. Automatic updates minimise the risk of you delaying or forgetting to apply an update, and help restrict the ability of attackers to gain control of your computer and sensitive personal and financial data.

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

Apple has issued advice and released security updates for macOS Server, macOS Sierra, Safari and iCloud for Windows. You are advised to review the Apple advisories and apply the necessary updates.

Mozilla has released advisories about updates to address vulnerabilities in Firefox and Firefox ESR. You are advised to read the advisories and apply the necessary updates.
