Hi,

The following vulnerability was published for sssd.

CVE-2018-10852[0]:
| 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.

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
