As reported by colleagues at Bleeping Computer, new serious vulnerabilities have recently been discovered affecting a large number of HP printer models that are part of the LaserJet Pro, Pagewide Pro, OfficeJet, Enterprise, Large Format and Deskjet lines.

The first , plotted as CVE-2022-3942 and reported with a severity score of 8.4 (high), relates to a buffer overflow that could lead to remote code execution on the affected machine. Discovered by Trend Micro's Zero Day Initiative team, this bug can be exploited with the use of Link-Local Multicast Name Resolution or LLMNR. HP promptly released updated firmware for most affected products, while unpatched products are advised to disable LLMNR from network settings.
