Canon published a security advisory describing seven critical (CVSS 9.8) buffer overflow and memory-corruption vulnerabilities in various imageCLASS, i‑SENSYS and Satera printer models (firmware v06.02 and earlier) that allow unauthenticated remote attackers to trigger arbitrary code execution or DoS; Canon recommends installing updated firmware and isolating devices behind routers/firewalls.
