There are 6 open security issues in buster.
6 issues left for the package maintainer to handle:
- CVE-2019-20485:
(needs triaging)
qemu/qemu_driver.c in libvirt before 6.0.0 mishandles the holding of a monitor job during a query to a guest agent, which allows attackers to cause a denial of service (API blockage).
- CVE-2020-10703:
(needs triaging)
A NULL pointer dereference was found in the libvirt API responsible introduced in upstream version 3.10.0, and fixed in libvirt 6.0.0, for fetching a storage pool based on its target path. In more detail, this flaw affects storage pools created without a target path such as network-based pools like gluster and RBD. Unprivileged users with a read-only connection could abuse this flaw to crash the libvirt daemon, resulting in a potential denial of service.
- CVE-2020-12430:
(needs triaging)
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-2020-25637:
(needs triaging)
A double free memory issue was found to occur in the libvirt API, in versions before 6.8.0, responsible for requesting information about network interfaces of a running QEMU domain. This flaw affects the polkit access control driver. Specifically, clients connecting to the read-write socket with limited ACL permissions could use this flaw to crash the libvirt daemon, resulting in a denial of service, or potentially escalate their privileges on the system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
- CVE-2021-3631:
(needs triaging)
- CVE-2021-3667:
