qemu-kvm: Out-of-bounds read when creating weird vga screen surface
Integer overflow in the VGA module in QEMU allows local guest OS users to cause a denial of service (out-of-bounds read and QEMU process crash) by editing VGA registers in VBE mode.
An integer overflow flaw and an out-of-bounds read flaw were found in the way QEMU's VGA emulator set certain VGA registers while in VBE mode. A privileged guest user could use this flaw to crash the QEMU process instance.

CVE-2016-3712 qemu-kvm: Out-of-bounds read when creating weird vga screen surface
Qemu VGA module allows guest to edit certain registers in 'vbe' and 'vga'
modes. ie. guest could set certain 'VGA' registers while in 'VBE' mode. This
leads to potential integer overflow or OOB read access issues in Qemu,
A privileged guest user could use this flaw to crash the Qemu process on the
host resulting in DoS.
