"The remote NewStart CGSL host, running version MAIN 6.06, 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 these issues but has instead relied only on the application's self-reported version
number.");
