medium Nessus Plugin ID 103538
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Virtuozzo host is missing a security update.


According to the version of the ksm-vz / prl-disp-legacy / prl-disp-service / etc packages installed, the Virtuozzo installation on the remote host is affected by the following vulnerability :

- QEMU (aka Quick Emulator), when built with the VGA display emulator support, allows local guest OS privileged users to cause a denial of service (out-of-bounds read and QEMU process crash) via vectors involving display update.

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


Update the affected ksm-vz / prl-disp-legacy / prl-disp-service / etc package.
