Oracle Linux 6 : spice-server (ELSA-2016-1204)

This script is Copyright (C) 2016 Tenable Network Security, Inc.

Synopsis :

The remote Oracle Linux host is missing one or more security updates.

Description :

From Red Hat Security Advisory 2016:1204 :

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

Red Hat Product Security has rated this update as having a security
impact of Important. 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 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.

Security Fix(es) :

* A memory allocation flaw, leading to a heap-based buffer overflow,
was found in spice's smartcard interaction, which runs under the
QEMU-KVM context on the host. A user connecting to a guest VM using
spice could potentially use this flaw to crash the QEMU-KVM process or
execute arbitrary code with the privileges of the host's QEMU-KVM
process. (CVE-2016-0749)

* A memory access flaw was found in the way spice handled certain
guests using crafted primary surface parameters. A user in a guest
could use this flaw to read from and write to arbitrary memory
locations on the host. (CVE-2016-2150)

The CVE-2016-0749 issue was discovered by Jing Zhao (Red Hat) and the
CVE-2016-2150 issue was discovered by Frediano Ziglio (Red Hat).
