The System Security Services Daemon (SSSD) service provides a set of daemons to manage access to remote directories and authentication mechanisms. It also provides the Name Service Switch (NSS) and the Pluggable Authentication Modules (PAM) interfaces toward the system, and a pluggable back-end system to connect to multiple different account sources.

Security Fix(es):

  • sssd: shell command injection in sssctl (CVE-2021-3621)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es):

  • Memory leak in the simple access provider (BZ#1964415)

  • id lookup is failing intermittently (BZ#1968330)

  • SSSD is NOT able to contact the Global Catalog when local site is down (BZ#1973796)

  • Missing search index for originalADgidNumber (BZ#1988463)
