AnalysisAI
Canon Small Office Multifunction Printers and Laser Printers are vulnerable to a buffer overflow in WSD print job processing that allows remote attackers to execute arbitrary code or cause denial of service.
Technical ContextAI
The Web Services on Devices (WSD) print job processing in affected Canon printers fails to validate input buffer sizes (CWE-787), allowing an out-of-bounds write when processing specially crafted print jobs.
RemediationAI
Apply Canon firmware updates. Isolate printers on a dedicated network segment with restricted access.
