Doc Text:
A simulator escape vulnerability has been identified in Spim Simulator, which occurs in the READ_STRING_SYSCALL system call of the SPIM simulator virtual machine. When an attempt is made to set the starting write address at the boundary of the virtual machine's memory, and the write length exceeds the virtual machine's memory range, a heap buffer overflow occurs during the READ_STRING_SYSCALL system call. This corrupts the host's memory, which then allows for an escape from the virtual machine.
