Denial of service via compact font overflow
Published Jun 30, 2023 · Updated Dec 4, 2024
Stack-based buffer overflow in the compact font parser in HP LaserJet Pro firmware allows remote attackers to interrupt printing. The parser writes attacker-controlled compact-font data beyond a stack buffer, but HP has not identified the affected routine or exposed field. Exploitation requires adjacent-network access and no authentication; HP identifies denial of service but does not state whether the device hangs, crashes, or reboots.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
