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.

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

Buffer overflow vulnerability in TIFF data EXIF tag processing in multiple Canon Satera, Color imageCLASS, and i-SENSYS printer models allows a network-adjacent attacker to cause denial of service or potentially execute arbitrary code via specially crafted TIFF image files.

MitigationUpdate affected printer firmware to a version later than v05.04; if immediate update is not possible, isolate vulnerable devices on a restricted network segment to limit exposure.

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 device label on the printer or access the web interface (http://[printer-ip]) to view the product name under the General or Device Information section
    Affected if model is one of Canon MF455dw, MF453dw, MF452dw, MF451dw, MF465dw, MF462dw, MF656cdw, or MF654cdw
  2. Check firmware version
    In the printer web interface, navigate to Settings > Device Settings or Firmware Update section to view the current firmware version; alternatively, print a configuration page from the control panel
    Affected if firmware version is 05.04 or lower (e.g., 05.04, 05.03, 05.02, etc.)
  3. Confirm TIFF/EXIF processing capability is in use
    The vulnerability is triggered when the printer processes TIFF image files containing EXIF data; check if the printer is configured to accept print jobs from network sources or scan-to-email/file workflows that handle TIFF images
    Affected if the printer accepts network print jobs or processes TIFF images from external sources

You are affected if you have a Canon MF455dw/453dw/452dw/451dw/465dw/462dw/656cdw/654cdw printer with firmware version 05.04 or lower and the device processes TIFF images from network sources.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

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

Update affected printer firmware to a version later than v05.04; if immediate update is not possible, isolate vulnerable devices on a restricted network segment to limit exposure.

Recommended fix Moderate confidence

Firmware version > 05.04 (specific fixed version available on Canon support sites)

  1. 1. Identify the exact model number of the Canon device from the affected product list (MF455dw, MF453dw, MF452dw, MF451dw, MF465dw, MF462dw, MF656cdw, MF654cdw, or related regional variants)
  2. 2. Check the current firmware version installed on the device through the device's control panel or web interface
  3. 3. Navigate to the official Canon support website for your region (canon.jp, www.usa.canon.com, or www.canon-europe.com depending on your location)
  4. 4. Locate the firmware download section for your specific model
  5. 5. Download the latest firmware version available for your device model
  6. 6. Follow Canon's firmware update instructions, typically involving uploading the firmware file through the device's web interface or USB connection
  7. 7. After updating, verify the firmware version has changed from <=05.04 to a higher version
Caveat Firmware updates may reset device settings; backup configuration if possible before updating
