VULHUB ™

It is reported that Ricoh 450/455 printers are susceptible to a remote denial of service vulnerability. This issue is due to a failure of the device to properly handle exceptional ICMP packets. Remote attackers may exploit this vulnerability to restart affected devices. Repeated packets may be utilized to sustain the condition, causing the device to repeatedly restart. Source addresses of the malicious ICMP packets may also be spoofed, reducing the likelihood of locating, or blocking access to the attacker. Due to code reuse among devices, it is likely that other printers are also affected.
