An updated spice package that fixes one security issue is now available for
Red Hat Enterprise Linux 7.

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

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