CVE-2016-7170

Priority
Description
The vmsvga_fifo_run function in hw/display/vmware_vga.c in QEMU (aka Quick
Emulator) allows local guest OS administrators to cause a denial of service
(out-of-bounds write and QEMU process crash) via vectors related to
cursor.mask[] and cursor.image[] array sizes when processing a
DEFINE_CURSOR svga command.
Notes
tyhicksvmsvga_fifo_run() in 12.04's qemu-kvm is slightly different but
still looks to be affected
