Linux Distros Unpatched Vulnerability : CVE-2020-12430

medium Nessus Plugin ID 223274

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - 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 relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
