CVE-2018-10852 (opens in a new tab)How to fix?
Upgrade Oracle:7 sssd-dbus to version 0:1.16.2-13.el7 or higher.
This issue was patched in ELSA-2018-3158.
NVD Description
Note: Versions mentioned in the description apply only to the upstream sssd-dbus package and not the sssd-dbus package as distributed by Oracle.
See How to fix? for Oracle:7 relevant fixed versions and status.
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.
