IBM OPENBMC FW1120.00 through FW1120.01, FW1110.00 through FW1110.31, and FW1060.00 through FW1060.81 is affected by a vulnerability in the BMC firmware management interface. The host system can cause the BMC firmware management service to crash or allow a limited amount of BMC internal memory to be read, resulting in a confidentiality and availability impact to the managed system.
