Descriptionfprintd through 1.94.3 lacks a security attention mechanism, and thus unexpected actions might be authorized by "auth sufficient" for Sudo. NOTE: the supplier disputes this because they believe issue resolution would involve modifying the PAM configuration to restrict to front-ends that implement a proper attention mechanism, not modifying or fprintd.
