Canon U.S.A., Inc. has recently become aware of potential multiple buffer overflow vulnerabilities in the Canon Laser Printers/Inkjet Printers and Small Office Multifunctional Printers listed under Affected models below. If the product is connected directly to the internet without using a wired or Wi-Fi router, a third party could potentially execute arbitrary code or the product could be subjected to a Denial-of-Service (DoS) attack. In addition, there is the potential for arbitrary files to be installed by a third party due to improper authentication of the Remote User Interface (printer web portal).:

* For these models, the updated firmware will not be available on the Canon website; however it is recommended to use the Firmware Update feature on your device while connected to the network to update to the latest version.

Furthermore, if you have not done so already, we recommend that you set up a private IP address for products and create a network environment with a firewall or Wi-Fi router that can restrict network access.
