sssd-1.16.5-10.16.0.2.el7.AXS7

Provides a set of daemons to manage access to remote directories and
authentication mechanisms. It provides an NSS and PAM interface toward
the system and a pluggable backend system to connect to multiple different
account sources. It is also the basis to provide client auditing and policy
services for projects like FreeIPA.

The sssd subpackage is a meta-package that contains the deamon as well as all
the existing back ends.

* CVE-2025-11561: prevent unexpected Kerberos principal-to-account mappings
when SSSD's localauth plugin cannot resolve a principal

CVE(s):
CVE-2025-11561
A flaw was found in the integration of Active Directory and the System Security Services Daemon (SSSD) on Linux systems. In default configurations, the Kerberos local authentication plugin (sssd_krb5_localauth_plugin) is enabled, but a fallback to the an2ln plugin is possible. This fallback allows an attacker with permission to modify certain AD attributes (such as userPrincipalName or samAccountName) to impersonate privileged users, potentially resulting in unauthorized access or privilege escalation on domain-joined Linux hosts.
