medium Nessus Plugin ID 24901

Language:

Synopsis

The remote printer service is prone to a denial of service attack.

Description

The version of CUPS installed on the remote host suffers from a design flaw involving SSL auto-detection. By establishing a connection to a port on which the application attempts to auto-detect SSL and sending a single character, an unauthenticated, remote attacker can leverage this flaw to cause subsequent connections to hang until the first connection is closed.

Solution

Upgrade to CUPS version 1.2.7 or later.
