Ubuntu 14.04 LTS / 16.04 LTS : cups vulnerability (USN-3577-1)

Medium Nessus Plugin ID 106929


The remote Ubuntu host is missing a security-related patch.


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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected cups package.
