Red Hat Security Advisory 2016-1943-01 – KVM is a full virtualization solution for Linux on x86 hardware. Using KVM, one can run multiple virtual machines running unmodified Linux or Windows images. Each virtual machine has private virtualized hardware: a network card, disk, graphics adapter, etc. Security Fix: An out-of-bounds read/write access flaw was found in the way QEMU’s VGA emulation with VESA BIOS Extensions support performed read/write operations using I/O port methods. A privileged guest user could use this flaw to execute arbitrary code on the host with the privileges of the host’s QEMU process.
