RedHat: RHSA-2016-1001:01 Important: qemu-kvm-rhev security update
Summary
KVM (Kernel-based Virtual Machine) is a full virtualization solution for
Linux on AMD64 and Intel 64 systems. The qemu-kvm-rhev package provides the
user-space component for running virtual machines using KVM in environments
managed by Red Hat Enterprise Virtualization Manager.
Security Fix:
* An out-of-bounds read/write access flaw was found in the way QEMU's VGA
emulation with VESA BIOS Extensions (VBE) 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. (CVE-2016-3710)
Red Hat would like to thank Wei Xiao (360 Marvel Team) and Qinghao Tang
(360 Marvel Team) for reporting this issue.
