EulerOS Virtualization 2.10.0 : libvirt (EulerOS-SA-2022-2092)

medium Nessus Plugin ID 163166

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

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

 - A flaw was found in the libvirt nwfilter driver. The virNWFilterObjListNumOfNWFilters method failed to acquire the `driver->nwfilters` mutex before iterating over virNWFilterObj instances. There was no protection to stop another thread from concurrently modifying the `driver->nwfilters` object. This flaw allows a malicious, unprivileged user to exploit this issue via libvirt's API virConnectNumOfNWFilters to crash the network filter management daemon (libvirtd/virtnwfilterd). (CVE-2022-0897)

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.
