THE POTENTIAL VULNERABILITY SUMMARY

The affected printer has potential vulnerabilities which may cause a device stall, memory destruction, and network failure, but won't be exploited by a springboard attack or cause confidential information leakage. Please visit here.

This vulnerability will not affect devices connected to the customer's network if the network is properly configured against external attacks. Ricoh recommends always using best practices for network protection, including:

  1. When the device is connected to a network, ensure that the network is protected, for example, by a firewall.
  2. Install the device in a secure network where users restrictions are in place.

RESOLUTION

Please download the updated firmware as below. Ricoh will release further updated firmware on the driver site as it is available.
