* This vulnerability requires access to the libvirt socket, normally in /var/run/libvirt/libvirt_sock_ro. Typically in hypervisor environments, local user accounts are not supported so no untrusted users should be able to access this socket.
* Kylin Gluster Storage 3 is not affected by this vulnerability as libvirtd daemon is not shipped in Gluster.

The virConnectBaselineHypervisorCPU() and virConnectCompareHypervisorCPU() libvirt APIs accept an "emulator" argument to specify the program providing emulation for a domain. Since v1.2.19, libvirt will execute that program to probe the domain's capabilities. Read-only clients could specify an arbitrary path for this argument, causing libvirtd to execute a crafted executable with its own privileges.
