The vmsvga_fifo_run function in hw/display/vmware_vga.c in QEMU allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) via a VGA command.
Weakness
The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop.
