Synopsis

The remote Red Hat host is missing a security update for qemu-kvm-rhev.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2017:2628 advisory.

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

Security Fix(es):

* An assertion-failure flaw was found in the Network Block Device (NBD) server's initial connection negotiation, where the I/O co-routine was undefined. This could crash the qemu-nbd server if a client sent unexpected data during connection negotiation. A remote user or process could use this flaw to crash the qemu-nbd server resulting in denial of service. (CVE-2017-7539)

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

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

Solution

Update the RHEL qemu-kvm-rhev package based on the guidance in RHSA-2017:2628.
