(RHSA-2018:2731) Important: spice and spice-gtk security update

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.

The spice-gtk packages provide a GIMP Toolkit (GTK+) widget for Simple Protocol for Independent Computing Environments (SPICE) clients. Both Virtual Machine Manager and Virtual Machine Viewer can make use of this widget to access virtual machines using the SPICE protocol.

Security Fix(es):

• spice: Missing check in demarshal.py:write_validate_array_item() allows for buffer overflow and denial of service (CVE-2018-10873)
