Authenticated stack based buffer overflow affecting multiple models from Brother Industries, Ltd, FUJIFILM Business Innovation, Ricoh, and Konica Minolta, Inc.
Published Jun 25, 2025 · Updated Apr 7, 2026
An authenticated attacker may trigger a stack based buffer overflow by performing a malformed request to either the HTTP service (TCP port 80), the HTTPS service (TCP port 443), or the IPP service (TCP port 631). The malformed request will contain an empty Origin header value and a malformed Referer header value. The Referer header value will trigger a stack based buffer overflow when the host value in the Referer header is processed and is greater than 64 bytes in length.
