CVE-2018-10852
Description
The UNIX pipe which sudo uses to contact SSSD and read the available sudo rules from SSSD utilizes too broad of a set of permissions. Any user who can send a message using the same raw protocol that sudo and SSSD use can read the sudo rules available for any user.

Red Hat Satellite since version 6.4 uses sssd from the Red Hat Enterprise Linux repositories, where this vulnerability is fixed.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
