Mozilla issues security update for Thunderbird email application

Priority Level: 
5 January 2017

Mozilla has released a security update to address vulnerabilities in its Thunderbird email application. You should apply this update as soon as possible to minimise risk to your computer and information.

Mozilla has provided advice about the security vulnerabilities fixed in Thunderbird 45.6.

You are advised to review security advisories 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.
