Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2016:2706 advisory.

KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm-rhev package provides the user-space component for running virtual machines using KVM in environments managed by Red Hat Enterprise Virtualization Manager.

The following packages have been upgraded to a newer upstream version: qemu-kvm-rhev (2.6.0). (BZ#1386377)

Security Fix(es):

* An out-of-bounds flaw was found in the QEMU emulator built using 'address_space_translate' to map an address to a MemoryRegionSection. The flaw could occur while doing pci_dma_read/write calls, resulting in an out-of-bounds read-write access error. A privileged user inside a guest could use this flaw to crash the guest instance (denial of service). (CVE-2015-8817, CVE-2015-8818)

Red Hat would like to thank Donghai Zdh of Alibaba Inc. for reporting this issue.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
