CVE-2018-16883 sssd: Information leak in infopipe due to an improper uid restriction
It was discovered that sssd versions prior to 2.0.0 did not properly restrict access to the infopipe according to the "allowed_uids" parameter. If sensitive information were stored in the user directory, this could be inadvertently disclosed to local attackers.

Mitigation:
This vulnerability is only exposed if the infopipe service is enabled (enabled by default in Red Hat Enterprise Linux 7, disabled by default in Red Hat Enterprise Linux 6), and `[ifp].allowed_uids` is relied upon to protect sensitive information in the user directory.
