An attacker with access to the libvirtd socket could use this to probe the existence of arbitrary files, cause a denial of service or otherwise cause libvirtd to execute arbitrary programs. * CVE-2019-10167: Prevent an arbitrary code execution vulnerability via the API where a user-specified binary used 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.
