Today, December 13, 2016, Canonical published a new USN (Ubuntu Security Notice) advisory to inform users of the popular Ubuntu Linux operating system about the availability of Mozilla Firefox 50.1.0 in the software repositories.

Mozilla released the Firefox 50.1.0 web browser a couple of days ago, and it looks like they patched a total of 13 security vulnerabilities, which could have been used by an attacker to crash the application or run programs as your login if the users were to open a malicious website.

"Multiple security vulnerabilities were discovered in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to conduct cross-site scripting (XSS) attacks, obtain sensitive information, cause a denial of service via application crash, or execute arbitrary code," reads USN-3155-1.

Canonical urges users to update the Firefox web browser immediately

These multiple security issues affect all the supported Ubuntu Linux operating systems, including Ubuntu 16.10 (Yakkety Yak), Ubuntu 16.04 LTS (Xenial Xerus), Ubuntu 14.04 LTS (Trusty Tahr), and Ubuntu 12.04 LTS (Precise Pangolin), as well as its official derivatives, such as Kubuntu, Xubuntu, Ubuntu GNOME, Lubuntu, etc.

Canonical urges users of the popular Linux OS to update the Mozilla Firefox packages as soon as possible. Firefox 50.1.0 is now available in the stable software repositories of the Ubuntu versions mentioned above, so make sure that you run a full system update to install it.

Of course, Mozilla Firefox 50.1.0 also arrived on the repos of various other popular GNU/Linux distributions, such as Arch Linux, so you should update immediately. Alternatively, you can download the Mozilla Firefox 50.1.0 source and binary packages right now from our website.
