Summary:The remote host is missing an update for the 'qemu-kvm'; package(s) announced via the referenced advisory.
The remote host is missing an update for the 'qemu-kvm'
package(s) announced via the referenced advisory.

Vulnerability Insight:
KVM (Kernel-based Virtual Machine) is a full virtualization solution for
Linux on AMD64 and Intel 64 systems. The qemu-kvm package provides the
user-space component for running virtual machines using KVM.

An information leak flaw was found in the way QEMU's VGA emulator accessed
frame buffer memory for high resolution displays. A privileged guest user
could use this flaw to leak memory contents of the host to the guest by
setting the display to use a high resolution in the guest. (CVE-2014-3615)

This issue was discovered by Laszlo Ersek of Red Hat.

This update also fixes the following bug:

* This update fixes a regression in the scsi_block_new_request() function,
which caused all read requests to through SG_IO if the host cache was not
used. (BZ#1141189)

All qemu-kvm users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. After installing this
update, shut down all running virtual machines. Once all virtual machines
have shut down, start them again for this update to take effect.

Affected Software/OS:
qemu-kvm on Red Hat Enterprise Linux Server (v. 7)

Please Install the Updated Packages.
