3. Description:

 

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.

 

4. Solution:

 

Before applying this update, make sure all previously released errata

relevant to your system have been applied.

 

This update is available via the Red Hat Network. Details on how to
