NVD Description

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

A flaw was found in SSSD. A use-after-free vulnerability exists in the Kerberos Credential Manager (KCM) responder during Kerberos ticket-granting ticket (TGT) renewal, where a deferred callback accesses memory that has already been released. An authenticated local user with a renewable Kerberos ticket can trigger this issue on systems configured with KCM renewal, causing the KCM responder service to crash and resulting in a Denial of Service (DoS).
