EulerOS Virtualization for ARM 64 3.0.1.0 : libvirt (EulerOS-SA-2019-1394)

high Nessus Plugin ID 124897

Synopsis

The remote EulerOS Virtualization for ARM 64 host is missing multiple security updates.

Description

According to the versions of the libvirt packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

 - util/virlog.c in libvirt does not properly determine the hostname on LXC container startup, which allows local guest OS users to bypass an intended container protection mechanism and execute arbitrary commands via a crafted NSS module.(CVE-2018-6764)

 - qemu/qemu_monitor.c in libvirt allows attackers to cause a denial of service (memory consumption) via a large QEMU reply.(CVE-2018-5748)

 - libvirt version 2.3.0 and later is vulnerable to a bad default configuration of 'verify-peer=no' passed to QEMU by libvirt resulting in a failure to validate SSL/TLS certificates by default.(CVE-2017-1000256)

 - An incomplete fix for CVE-2018-5748 that affects QEMU monitor leading to a resource exhaustion but now also triggered via QEMU guest agent.(CVE-2018-1064)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected libvirt packages.
