Mozilla Foundation releases security updates for Firefox and Thunderbird
5 December 2014
Alert Priority High
The Mozilla Foundation has released updates to address a range of vulnerabilities in the widely used Firefox and Thunderbird products.
Announcement of the vulnerabilities reinforces the importance of users applying updates to protect their systems from malicious intrusion.
The vulnerabilities could be exploited to allow an attacker to obtain sensitive information or effectively disable a computer or network.
The Mozilla Foundation rated three of the vulnerabilities as ‘critical’, meaning they could be used to run malicious code and install software without requiring any user interaction beyond normal browsing.
It ranked another three vulnerabilities as ‘high’, meaning they could be used to gather sensitive data from sites in other windows or inject data or code into those sites, without requiring any user interaction other than normal browsing.
The remaining three were ‘moderate’, meaning they only worked in uncommon configurations or required the user to perform unusual activities.
