Analysis
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 Context
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.
Affected Products
['Canon Small Office Multifunction Printers', 'Canon Laser Printers']
