NVD Description
Note: Versions mentioned in the description apply only to the upstream libvirt-daemon-driver-network package and not the libvirt-daemon-driver-network package as distributed by Oracle.
See How to fix? for Oracle:7 relevant fixed versions and status.
It was discovered that libvirtd before versions 4.10.1 and 5.4.1 would permit read-only clients to use the virDomainSaveImageGetXMLDesc() API, specifying an arbitrary path which would be accessed with the permissions of the libvirtd process. An attacker with access to the libvirtd socket could use this to probe the existence of arbitrary files, cause denial of service or cause libvirtd to execute arbitrary programs.
