Canonical has announced that a Bind vulnerability has been found and fixed for Ubuntu 14.10, Ubuntu 14.04 LTS, Ubuntu 12.04 LTS operating systems.

It has been revealed that Bind could have been made to crash if it received specially crafted network traffic (bind9 - Internet Domain Name Server). The Ubuntu maintainers have pushed a new version of the library into the repositories.

"Jan-Piet Mens discovered that Bind incorrectly handled Trust Anchor Management. A remote attacker could use this issue to cause bind to crash, resulting in a denial of service," reads the security advisory. As you can see, this is a rather specific bug, but it doesn't hurt to update the system nonetheless.

For a more detailed description, you can see Canonical's security notification. Users are advised to upgrade their systems as soon as possible. You can either upgrade Ubuntu with the regular tool or you can also use the terminal to upgrade the system. Just enter these commands in a terminal near you:

[CODE=0]sudo apt-get update sudo apt-get dist-upgrade[CODE=1

In general, a standard system update will make all the necessary changes. This is not a critical component, so it's not necessary to also reboot the system.
