3. Description:

 

KVM (Kernel-based Virtual Machine) is a full virtualization solution for

Linux on AMD64 and Intel 64 systems. The qemu-kvm packages provide the

user-space component for running virtual machines using KVM.

 

Security Fix(es):

 

* 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 via 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.
