Description:
 The virConnectGetDomainCapabilities() libvirt API, versions 4.x.x before
 4.10.1 and 5.x.x before 5.4.1, accepts an "emulatorbin" 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.
