EulerOS Virtualization 2.5.0 : libvirt (EulerOS-SA-2018-1277)

high Nessus Plugin ID 117585

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the libvirt packages installed, the EulerOS Virtualization 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)

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.
