The Red Hat security team deemed this advisory irrelevant for RHEL:7.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libsss_nss_idmap-python package and not the libsss_nss_idmap-python package as distributed by RHEL.
A flaw was found in SSSD, where the sssctl command was vulnerable to shell command injection via the logs-fetch and cache-expire subcommands. This flaw allows an attacker to trick the root user into running a specially crafted sssctl command, such as via sudo, to gain root access. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
