Canonical has published details in a security notice about a Squid 3 vulnerability in Ubuntu 14.04 LTS and Ubuntu 12.04 LTS operating systems that has been found and fixed.

The Ubuntu developers have closed a small problem with Squid, which could have been made to crash, if it received specially crafted network traffic.

According to the security notice, "Matthew Daley discovered that Squid 3 did not properly perform input validation in request parsing. A remote attacker could send crafted Range requests to cause a denial of service."

For a more detailed description of the problems, you can see Canonical's security notification. Users should upgrade their Linux distribution in order to correct this issue.

The flaw can be fixed if you upgrade your system(s) to the latest squid3 packages specific to each distribution. To apply the patch, you can simply run the Update Manager application.

If you don't want to use the Software Updater, you can open a terminal and enter the following commands (you will need to be root):

code
sudo apt-get update
sudo apt-get dist-upgrade
In general, a standard system update will make all the necessary changes. You won't have to restart the PC in order to implement this fix.
