Thank you for using Canon Products.
Multiple cases of buffer overflow vulnerabilities have been found for Canon Laser Printers and Small Office Multifunction Printers.
These vulnerabilities indicate the possibility that if a product is connected directly to the Internet without using a router (wired or Wi-Fi), an unauthenticated remote attacker via the Internet may be able to execute arbitrary code and/or may be able to target the product in a Denial-of Service (DoS) attack.
There have been no reports of damage relating to this vulnerability. However, to enhance the security of the product, we advise customers to install the latest firmware available for the Affected Models provided below.
We also recommend customers to set a private IP address for the products and create a network environment with a firewall or Wired/Wi-Fi router that can restrict network access.
For details, please refer to the following link.
We will work towards further strengthening security measures to ensure that customers can continue using Canon products with peace of mind.
