Alert Priority High
16 December 2016

Apple, Joomla and Mozilla have released security updates to address vulnerabilities in their software products. You should apply these updates as soon as possible to minimise risk to your computers and information.

Apple has provided advice about updates to address vulnerabilities in Safari, iCloud for Windows, iTunes for Windows and macOS Sierra.

Joomla has released an update for its website content management system to address three security issues, while Mozilla has updated its Firefox and Firefox ESR web browser.

You are advised to review security bulletins from any vendor you use and apply their updates as soon as possible. Many vendors allow you to automate the process of updating their software.

Security updates address vulnerabilities in computer systems that remote attackers can otherwise use to gain access to systems 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.
