NVD Description

Note: Versions mentioned in the description apply only to the upstream sssd-client package and not the sssd-client package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

A flaw was found in sssd. A local user can cause a Denial of Service (DoS) by exhausting the responder service's available file descriptors (system handles used for open connections). By opening and maintaining many concurrent connections to a responder socket while continuing to queue new connection attempts, an attacker can trigger an unthrottled retry loop. This condition leads to high CPU utilization and stalls the service, preventing legitimate identity and authentication requests from being processed.
