                   Red Hat Security Advisory

Synopsis:          Important: spice-server security update
Advisory ID:       RHSA-2015:1889-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2015-1889.html
Issue date:        2015-10-12
CVE Names:         CVE-2015-5260 CVE-2015-5261 
=====================================================================

1. Summary:

An updated spice-server package that fixes two security issues is now
available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Important security
impact. Common Vulnerability Scoring System (CVSS) base scores, which give
detailed severity ratings, are available for each vulnerability from the
CVE links in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 6) - x86_64
Red Hat Enterprise Linux Desktop Optional (v. 6) - x86_64
Red Hat Enterprise Linux HPC Node (v. 6) - x86_64
Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64
Red Hat Enterprise Linux Server (v. 6) - x86_64
Red Hat Enterprise Linux Server Optional (v. 6) - x86_64
Red Hat Enterprise Linux Workstation (v. 6) - x86_64
Red Hat Enterprise Linux Workstation Optional (v. 6) - x86_64

3. Description:

The Simple Protocol for Independent Computing Environments (SPICE) is a
remote display protocol for virtual environments. SPICE users can access a
virtualized desktop or server from the local system or any system with
network access to the server. SPICE is used in Red Hat Enterprise Linux for
viewing virtualized guests running on the Kernel-based Virtual Machine
(KVM) hypervisor or on Red Hat Enterprise Virtualization Hypervisors.

A heap-based buffer overflow flaw was found in the way SPICE handled
certain guest QXL commands related to surface creation. A user in a guest
could use this flaw to read and write arbitrary memory locations on the
host. (CVE-2015-5261)

A heap-based buffer overflow flaw was found in the way spice handled
certain QXL commands related to the "surface_id" parameter. A user in a
guest could use this flaw to crash the host QEMU-KVM process or, possibly,
execute arbitrary code with the privileges of the host QEMU-KVM process.
(CVE-2015-5260)

These issues were discovered by Frediano Ziglio of Red Hat.

All spice-server users are advised to upgrade to this updated package,
which contains backported patches to correct these issues.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

For details on how to apply this update, refer to:

https://access.redhat.com/articles/11258

5. Bugs fixed (https://bugzilla.redhat.com/):

1260822 - CVE-2015-5260 spice: insufficient validation of surface_id parameter can cause crash
1261889 - CVE-2015-5261 spice: host memory access from guest using crafted images
