Ubuntu Security Notice USN-3577-1

20th February, 2018

cups vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

    Ubuntu 16.04 LTS
    Ubuntu 14.04 LTS


CUPS could be made to provide access to printers over the network.
Software description

    cups - Common UNIX Printing System(tm)


Jann Horn discovered that CUPS permitted HTTP requests with the Host
header set to "localhost.localdomain" from the loopback interface. If a
user were tricked in to opening a specially crafted website in their web
browser, an attacker could potentially exploit this to obtain sensitive
information or control printers, via a DNS rebinding attack.

Update instructions

The problem can be corrected by updating your system to the following package 

Ubuntu 16.04 LTS:
    cups 2.1.3-4ubuntu0.4 
Ubuntu 14.04 LTS:
    cups 1.7.2-0ubuntu1.9 

To update your system, please follow these instructions:

In general, a standard system update will make all the necessary changes.
