QEMU: VGA: reachable assert failure during display update
The vga display update in mis-calculated the region for the dirty bitmap snapshot in case split screen mode is used causing a denial of service (assertion failure) in the cpu_physical_memory_snapshot_get_dirty function.
An assert failure issue was found in the VGA display emulator built into the Quick emulator (QEMU). It could occur while updating graphics display, due to miscalculating region for dirty bitmap snapshot in split screen mode. A privileged user/process inside guest could use this flaw to crash the QEMU process on the host resulting in denial of service.

CVE-2017-13673 QEMU: VGA: reachable assert failure during display update
Quick emulator(Qemu) built with the VGA display emulator support is vulnerable
to an assert failure issue. It could occur while updating graphics display,
due to miscalculating region for dirty bitmap snapshot in split screen mode.
A privileged user/process inside guest could use this flaw to crash the Qemu
process on the host resulting in DoS.
