DescriptionIBM Power Systems Firmware FW1120.00, FW1110.00 through FW1110.30, FW1060.00 through FW1060.80, and FW950.00 through FW950.H2 is affected by a vulnerability in the ASMI web interface. An unauthenticated attacker on the management network can cause the ASMI web server to crash with possible memory corruption and generate an error log; hosted partitions are not affected. The ASMI web interface will restart automatically; however, repeated exploitation could result in a sustained loss of access to the ASMI management interface, resulting in an integrity and availability impact.
