Red Hat Security Advisory 2019-2229-01 - The spice-gtk packages provide a GIMP Toolkit widget for Simple Protocol for Independent Computing Environments clients. Both Virtual Machine Manager and Virtual Machine Viewer can make use of this widget to access virtual machines using the SPICE protocol. The libgovirt packages contain a library that allows applications to use the oVirt Representational State Transfer API to list virtual machines managed by an oVirt instance. The library is also used to get the connection parameters needed to establish a connection to the VMs using Simple Protocol For Independent Computing Environments or Virtual Network Computing . Issues addressed include a buffer overflow vulnerability.

====================================================================
1. Summary:

An update for spice-gtk, libgovirt, spice-vdagent, and virt-viewer is now
available for Red Hat Enterprise Linux 7.

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Client (v. 7) - x86_64
Red Hat Enterprise Linux Client Optional (v. 7) - x86_64
Red Hat Enterprise Linux Server (v. 7) - ppc64, ppc64le, s390x, x86_64

3. Description:

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.

The libgovirt packages contain a library that allows applications to use
the oVirt Representational State Transfer (REST) API to list virtual
machines (VMs) managed by an oVirt instance. The library is also used to
get the connection parameters needed to establish a connection to the VMs
using Simple Protocol For Independent Computing Environments (SPICE) or
Virtual Network Computing (VNC).

The spice-vdagent packages provide a SPICE agent for Linux guests.

The virt-viewer packages provide Virtual Machine Viewer, which is a
lightweight interface for interacting with the graphical display of a
virtualized guest.

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 CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.

Additional Changes:

For detailed information on changes in this release, see the Red Hat
Enterprise Linux 7.7 Release Notes linked from the References section.

4. Solution:
