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