"An update for spice-gtk is now available for Red Hat Enterprise Linux
6.

Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

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-client: Insufficient encoding checks for LZ can cause
different integer/buffer overflows (CVE-2018-10893)

For more details about the security issue(s), including the impact, a
