CVE-2018-10852
The UNIX pipe which sudo uses to contact SSSD and read the available
sudo rules from SSSD has too wide permissions, which means that anyone
who can send a message using the same raw protocol that sudo and SSSD
use can read the sudo rules available for any user. This affects
versions of SSSD before 1.16.3.
