RHBA-2018:1378 - Bug Fix Advisory

Topic

Updated spice packages that fix one bug and add one enhancement are now available for Red Hat Enterprise Linux 7.

Description

The Simple Protocol for Independent Computing Environments (SPICE) is a remote display system built for virtual environments which allows the user to view a computing 'desktop' environment not only on the machine where it is running, but from anywhere on the Internet and from a wide variety of machine architectures.

This update fixes the following bug:

• Previously, live migration of a guest virtual machine in some cases failed if the QXL driver was installed on the guest. This update fixes the spice-server library to avoid guest memory corruption, and the affected guests can now be live migrated successfully. (BZ#1572489)

In addition, this update adds the following enhancement:

• The TLS protocol version 1.0 has been disabled in the SPICE server. As a result, a client using TLS protocol version 1.0 can no longer connect to the SPICE server. (BZ#1551072)

Users of spice are advised to upgrade to these updated packages, which fix this bug and add this enhancement.
