Test ID:1.3.6.1.4.1.25623.1.0.871446
Category:Red Hat Local Security Checks
Title:RedHat Update for spice-server RHSA-2015:1715-01
Summary:The remote host is missing an update for the 'spice-server'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'spice-server'
package(s) announced via the referenced advisory.

Vulnerability Insight:
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 race condition flaw, leading to a heap-based memory corruption, was found
in spice's worker_update_monitors_config() function, which runs under the
QEMU-KVM context on the host. A user in a guest could leverage this flaw to
crash the host QEMU-KVM process or, possibly, execute arbitrary code with
the privileges of the host QEMU-KVM process. (CVE-2015-3247)

This issue was discovered by Frediano Ziglio of Red Hat.

All spice-server users are advised to upgrade to this updated package,
which contains a backported patch to correct this issue.

Affected Software/OS:
spice-server on Red Hat Enterprise Linux Desktop (v. 6),
Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)

Solution:
Please Install the Updated Packages.
