USN-3577-1: CUPS vulnerability
21 February 2018
CUPS could be made to provide access to printers over the network.
- 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.
