Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Buffer overflow in XPS data font processing of Small Office Multifunction Printers and Laser Printers(*) which may allow an attacker on the network segment to trigger the affected product being unresponsive or to execute arbitrary code. *: Satera MF656Cdw/Satera MF654Cdw firmware v05.04 and earlier sold in Japan. Color imageCLASS MF656Cdw/Color imageCLASS MF654Cdw/Color imageCLASS MF653Cdw/Color imageCLASS MF652Cdw/Color imageCLASS LBP633Cdw/Color imageCLASS LBP632Cdw firmware v05.04 and earlier sold in US. i-SENSYS MF657Cdw/i-SENSYS MF655Cdw/i-SENSYS MF651Cdw/i-SENSYS LBP633Cdw/i-SENSYS LBP631Cdw firmware v05.04 and earlier sold in Europe.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A buffer overflow vulnerability exists in the XPS data font processing component of multiple Canon Satera, Color imageCLASS, and i-SENSYS printer models running firmware v05.04 and earlier. By sending specially crafted XPS data containing malicious font information, an attacker on the same network segment can potentially cause the device to become unresponsive or achieve arbitrary code execution with elevated privileges.

MitigationApply the vendor-provided firmware update (v05.05 or later) when released. Until then, isolate affected devices on a restricted network segment to reduce attack surface.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify printer model
    Check the product label on the device or access the web interface (http://<printer-ip>) to view the model name under Device Information or Status
    Affected if Model is one of: Mf455dw, Mf453dw, Mf452dw, Mf451dw, Mf465dw, Mf462dw, Mf656cdw, or Mf654cdw
  2. Check installed firmware version
    Access the printer web interface, navigate to Settings or Device Information page to view the firmware version; alternatively, print a configuration page from the control panel
    Affected if Firmware version displayed is 05.04 or earlier (e.g., 05.04, 05.03, 05.02, etc.)
  3. Confirm network accessibility
    Ping the printer IP address or check if port 80/443 (web UI) or port 9100 (raw print) is responding from your workstation
    Affected if Printer is reachable from network segments that contain untrusted users or systems
  4. Verify XPS print job processing is enabled
    Check printer settings via web UI under Security or Port settings to confirm XPS/RAW printing ports are open; note that XPS processing is typically enabled by default for standard print workflows
    Affected if Printer accepts print jobs via XPS format or RAW port 9100 from network clients

Device is affected if it matches one of the listed models AND has firmware version 05.04 or earlier AND is accessible on a network where an attacker could send malicious XPS data.

dbcve · scoped
Upgrade available Upgrade to a release after 05.04
Interim mitigation

Apply the vendor-provided firmware update (v05.05 or later) when released. Until then, isolate affected devices on a restricted network segment to reduce attack surface.

Recommended fix Moderate confidence

Firmware version newer than 05.04 (check Canon support sites for exact latest version per model)

  1. 1. Identify the exact Canon printer model from the affected list (MF455dw, MF453dw, MF452dw, MF451dw, MF465dw, MF462dw, MF656cdw, MF654cdw or regional variants)
  2. 2. Visit the official Canon support website for your region (canon.jp, canon-europe.com, or usa.canon.com)
  3. 3. Navigate to the product support/ drivers and downloads section for your specific printer model
  4. 4. Locate the firmware update section and check for versions newer than 05.04
  5. 5. Download the latest firmware version available from Canon's official site
  6. 6. Follow Canon's provided firmware update instructions (typically involves connecting the printer via USB or network and running the firmware update utility)
  7. 7. After updating, verify the firmware version has changed from 05.04 or earlier to the newer version
  8. 8. Confirm the printer is functioning normally after the update
