libnss-libvirt: An issue was discovered in qemuDomainGetStatsIOThread in qemu/qemu_driver.c in libvirt 4.10.0 though 6.x before 6.1.0
CVE-2020-12430 is fixed in 16 products on 1 platform, first by libnss-libvirt 6.0.0-0ubuntu6, released April 28, 2020. It is not reported as exploited. Patch Radar priority: Routine.
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.
