February 21, 2018

cups vulnerability
==========================================================================

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

– Ubuntu 16.04 LTS
– Ubuntu 14.04 LTS

Summary:

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

Software Description:
– cups: Common UNIX Printing System(tm)

Details:

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.
(CVE-2017-18190)

Update instructions:

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

Ubuntu 16.04 LTS:
cups 2.1.3-4ubuntu0.4

Ubuntu 14.04 LTS:
cups 1.7.2-0ubuntu1.9

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