CVE-2025-1268
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 · uneditedOut-of-bounds vulnerability in EMF Recode processing of Generic Plus PCL6 Printer Driver / Generic Plus UFR II Printer Driver / Generic Plus LIPS4 Printer Driver / Generic Plus LIPSLX Printer Driver / Generic Plus PS Printer Driver / Generic FAX Printer Driver / UFRII LT Printer Driver / CARPS2 Printer Driver / PDF Driver / LIPS4 Printer Driver / LIPSLX Printer Driver / UFR II Printer Driver / PS Printer Driver / PCL6 Printer Driver
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 confidenceAn out-of-bounds memory access vulnerability exists in the EMF (Enhanced Metafile) Recode processing component of multiple Canon printer drivers. This flaw in the metafile parsing logic could allow an attacker to execute arbitrary code or cause a denial of service by sending specially crafted print jobs to affected devices.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify Canon printer drivers on the systemOpen Device Manager, expand 'Print queues', or check Programs and Features for Canon printer driver packages. On Windows, also check C:\Windows\System32\spool\drivers\x64\ for Canon driver files (*.sys, *.dll).Affected if Canon printer drivers are installed on the system
-
Determine the installed Canon driver versionRight-click the Canon printer in Device Manager, select Properties, then the Driver tab. Alternatively, right-click the driver DLL in the spooler folder and view Properties > Details > File version.Affected if The driver version falls within the affected version range or cannot be determined to be patched
-
Verify the EMF print processor is in useOpen Services > Print Spooler, note the executable path. Run 'printmanagement.msc' > Print Servers > Server Properties > Drivers. Select the Canon driver and check which print processor is associated, or run 'wmic printjob get /format:list' to see active jobs.Affected if The system uses the standard Windows EMF print processor or a Canon EMF-related processing component
-
Confirm print job submission accepts untrusted sourcesCheck if the print spooler is exposed to network or guest users. Review printer sharing settings and any direct IP printing ports (ports 9100, 631). Query registry HKLM\SYSTEM\CurrentControlSet\Control\Print\Monitors for USB/RAW ports that accept external jobs.Affected if The printer or print spooler accepts jobs from untrusted network sources or unauthenticated users
The environment is affected if Canon printer drivers are installed, the driver version is unpatched, and the system processes EMF print jobs from potentially untrusted 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.
From vendor dataApply vendor-supplied driver updates from Canon for all affected printer models. In enterprise environments, prioritize patching remote/exposed print servers and network printers, and consider network segmentation to limit exposure to untrusted print traffic.
