An update for sssd is now available for openEuler-22.03-LTS-SP4 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2025-2516 Final 1.0 1.0 2025-10-24 Initial 2025-10-24 2025-10-24 openEuler SA Tool V1.0 2025-10-24 sssd security update An update for sssd is now available for openEuler-22.03-LTS-SP4 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 back end system to connect to multiple different account sources. It is also the basis to provide client auditing and policy services for projects like FreeIPA. Security Fix(es): A flaw was found in the integration of Active Directory and the System Security Services Daemon (SSSD) on Linux systems. In default configurations, SSSD does not enable the Kerberos local authentication plugin (sssd_krb5_localauth_plugin), allowing an attacker with permission to modify certain AD attributes (such as userPrincipalName or samAccountName) to impersonate privileged users. This can result in unauthorized access or privilege escalation on domain-joined Linux hosts.(CVE-2025-11561) An update for sssd is now available for openEuler-22.03-LTS-SP4. openEuler Security has rated this update as having a security impact of high.
