Details

The vmsvga_fifo_read_raw function in hw/display/vmware_vga.c in QEMU allows local guest OS administrators to obtain sensitive host memory information or cause a denial of service (QEMU process crash) by changing FIFO registers and issuing a VGA command, which triggers an out-of-bounds read.
