medium Nessus Plugin ID 147389

Language:

Synopsis

The remote machine is affected by a vulnerability.

Description

The remote NewStart CGSL host, running version MAIN 6.02, has libvirt packages installed that are affected by a vulnerability:

 - An issue was discovered in qemuDomainGetStatsIOThread in qemu/qemu_driver.c in libvirt 4.10.0 though 6.x before 6.1.0. A memory leak was found in the virDomainListGetStats libvirt API that is responsible for retrieving domain statistics when managing QEMU guests. This flaw allows unprivileged users with a read- only connection to cause a memory leak in the domstats command, resulting in a potential denial of service. (CVE-2020-12430)

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

Solution

Upgrade the vulnerable CGSL libvirt packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
