The HP LaserJet MFP M232-M237 Printer Series may be vulnerable to a denial of service attack when a specially crafted request message is sent via Internet Printing Protocol (IPP).
Certain HP LaserJet printers may potentially experience a denial of service when a user sends a raw JPEG file to the printer. The printer displays a “JPEG Unsupported” message which may not clear, potentially blocking queued print jobs.
