CVE-2020-10703 Open this link in a new tabHow to fix?
Upgrade Oracle:7 libvirt-daemon-driver-storage-core to version 0:4.5.0-36.el7 or higher.
This issue was patched in ELSA-2020-4000.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libvirt-daemon-driver-storage-core package and not the libvirt-daemon-driver-storage-core package as distributed by Oracle.
See How to fix? for Oracle:7 relevant fixed versions and status.
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.
