Description

IBM Virtualization Management Interface FW1110.00 through FW1110.30, FW1120.00 through FW1120.00, and FW1060.00 through FW1060.80 is affected by a vulnerability in the Virtualization Management Interface (VMI). An attacker with authenticated administrator-level access can cause the VMI to crash. The VMI will restart automatically; however, repeated exploitation could result in a sustained availability impact.
