Description

Multics contains a flaw that may allow a local user to crash the machine. The issue occurs when a user causes the master mode procedure to enter a location improperly. When the index register zero is out of bounds, the processor registers are saved for debugging and control is transferred to "mxerror". By moving the signaller|0 with a bad value in index register zero, a user could crash the system.
