Virtuozzo 7 : qemu-img / qemu-kvm / qemu-kvm-common / etc (VZLSA-2017-0987)

critical Nessus Plugin ID 101452

Synopsis

The remote Virtuozzo host is missing a security update.

Description

An update for qemu-kvm is now available for Red Hat Enterprise Linux 7.

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.

Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm packages provide the user-space component for running virtual machines that use KVM.

Security Fix(es) :

* A heap buffer overflow flaw was found in QEMU's Cirrus CLGD 54xx VGA emulator's VNC display driver support; the issue could occur when a VNC client attempted to update its display after a VGA operation is performed by a guest. A privileged user/process inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process.
(CVE-2016-9603)

Note that Tenable Network Security has attempted to extract the preceding description block directly from the corresponding Red Hat security advisory. Virtuozzo provides no description for VZLSA advisories. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
