Details
It was discovered that libvirt incorrectly handled an active pool without a target path. A remote attacker could possibly use this issue to cause libvirt to crash, resulting in a denial of service. (CVE-2020-10703)
It was discovered that libvirt incorrectly handled memory when retrieving certain domain statistics. A remote attacker could possibly use this issue to cause libvirt to consume resources, resulting in a denial of service. This issue only affected Ubuntu 19.10. (CVE-2020-12430)
