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.
