HP Releases Printer Firmware To Address Critical Threats

Yesterday HP released firmware to address critical threats that cover popular LaserJet printer & MFP models. The threats have CVSS scores of 7.5, 8.4, and 9.8. If these patches are not applied, you may be leaving your printers vulnerable to information disclosure, denial of service, or remote code execution.

In certain HP Enterprise and HP LaserJet Pro printers, one of the threats can be mitigated by disabling LLMNR in network settings.

See below links for details on the threat, how to access the firmware update and instructions on disabling LLMNR:
