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.\r\n\r\nSecurity Fix(es):\n\nA flaw was found in SSSD. The sss_nss_protocol_parse_addr() function in the NSS responder does not validate the addrlen field against the remaining packet body size. A local attacker can exploit this via a crafted GETHOSTBYADDR request to the NSS responder socket, causing an out-of-bounds read and process crash, resulting in a denial of service.(CVE-2026-68742)\n\nA flaw was found in SSSD. The sss_nss_protocol_fill_initgr() function in the NSS responder pre-allocates reply space for all group entries but does not shrink the packet when groups are skipped, causing uninitialized heap bytes to be transmitted to the client. A local attacker can exploit this to disclose cached directory data and heap layout information from the sssd_nss process.(CVE-2026-68744)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP3","name":"sssd","purl":"pkg:rpm/openEuler/sssd&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.9.4-24.oe2403sp3"}]}],"ecosystem_specific":{"aarch64":["libipa_hbac-2.9.4-24.oe2403sp3.aarch64.rpm","libipa_hbac-devel-2.9.4-24.oe2403sp3.aarch64.rpm","libsss_autofs-2.9.4-24.oe2403sp3.aarch64.rpm","libsss_certmap-2.9.4-24.oe2403sp3.aarch64.rpm","libsss_certmap-devel-2.9.4-24.oe2403sp3.aarch64.rpm","libsss_idmap-2.9.4-24.oe2403sp3.aarch64.rpm","libsss_idmap-devel-2.9.4-24.oe2403sp3.aarch64.rpm","libsss_nss_idmap-2.9.4-24.oe2403sp3.aarch64.rpm","libsss_nss_idmap-devel-2.9.4-24.oe2403sp3.aarch64.rpm","libsss_sudo-2.9.4-24.oe2403sp3.aarch64.rpm","python3-libipa_hbac-2.9.4-24.oe2403sp3.aarch64.rpm","python3-libsss_nss_idmap-2.9.4-24.oe2403sp3.aarch64.rpm","python3-sss-2.9.4-24.oe2403sp3.aarch64.rpm","python3-sss-murmur-2.9.4-24.oe2403sp3.aarch64.rpm","sssd-2.9.4-24.oe2403sp3.aarch64.rpm","sssd-ad-2.9.4-24.oe2403sp3.aarch64.rpm","sssd-client-2.9.4-24.oe2403sp3.aarch64.rpm","sssd-common-2.9.4-24.oe2403sp3.aarch64.rpm","sssd-common-pac-2.9.4-24.oe2403sp3.aarch64.rpm","sssd-dbus-2.9.4-24.oe2403sp3.aarch64.rpm","sssd-debuginfo-2.9.4-24.oe2403sp3.aarch64.rpm","sssd-debugsource-2.9.4-24.oe2403sp3.aarch64.rpm","sssd-idp-2.9.4-24.oe2403sp3.aarch64.rpm","sssd-ipa-2.9.4-24.oe2403sp3.aarch64.rpm","sssd-kcm-2.9.4-24.oe2403sp3.aarch64.rpm","sssd-krb5-2.9.4-24.oe2403sp3.aarch64.rpm","sssd-krb5-common-2.9.4-24.oe2403sp3.aarch64.rpm","sssd-ldap-2.9.4-24.oe2403sp3.aarch64.rpm","sssd-nfs-idmap-2.9.4-24.oe2403sp3.aarch64.rpm","sssd-proxy-2.9.4-24.oe2403sp3.aarch64.rpm","sssd-tools-2.9.4-24.oe2403sp3.aarch64.rpm","sssd-winbind-idmap-2.9.4-24.oe2403sp3.aarch64.rpm"],"noarch":["python3-sssdconfig-2.9.4-24.oe2403sp3.noarch.rpm","sssd-help-2.9.4-24.oe2403sp3.noarch.rpm"],"src":["sssd-2.9.4-24.oe2403sp3.src.rpm"],"x86_64":["libipa_hbac-2.9.4-24.oe2403sp3.x86_64.rpm","libipa_hbac-devel-2.9.4-24.oe2403sp3.x86_64.rpm","libsss_autofs-2.9.4-24.oe2403sp3.x86_64.rpm","libsss_certmap-2.9.4-24.oe2403sp3.x86_64.rpm","libsss_certmap-devel-2.9.4-24.oe2403sp3.x86_64.rpm","libsss_idmap-2.9.4-24.oe2403sp3.x86_64.rpm","libsss_idmap-devel-2.9.4-24.oe2403sp3.x86_64.rpm","libsss_nss_idmap-2.9.4-24.oe2403sp3.x86_64.rpm","libsss_nss_idmap-devel-2.9.4-24.oe2403sp3.x86_64.rpm","libsss_sudo-2.9.4-24.oe2403sp3.x86_64.rpm","python3-libipa_hbac-2.9.4-24.oe2403sp3.x86_64.rpm","python3-libsss_nss_idmap-2.9.4-24.oe2403sp3.x86_64.rpm","python3-sss-2.9.4-24.oe2403sp3.x86_64.rpm","python3-sss-murmur-2.9.4-24.oe2403sp3.x86_64.rpm","sssd-2.9.4-24.oe2403sp3.x86_64.rpm","sssd-ad-2.9.4-24.oe2403sp3.x86_64.rpm","sssd-client-2.9.4-24.oe2403sp3.x86_64.rpm","sssd-common-2.9.4-24.oe2403sp3.x86_64.rpm","sssd-common-pac-2.9.4-24.oe2403sp3.x86_64.rpm","sssd-dbus-2.9.4-24.oe2403sp3.x86_64.rpm","sssd-debuginfo-2.9.4-24.oe2403sp3.x86_64.rpm","sssd-debugsource-2.9.4-24.oe2403sp3.x86_64.rpm","sssd-idp-2.9.4-24.oe2403sp3.x86_64.rpm","sssd-ipa-2.9.4-24.oe2403sp3.x86_64.rpm","sssd-kcm-2.9.4-24.oe2403sp3.x86_64.rpm","sssd-krb5-2.9.4-24.oe2403sp3.x86_64.rpm","sssd-krb5-common-2.9.4-24.oe2403sp3.x86_64.rpm","sssd-ldap-2.9.4-24.oe2403sp3.x86_64.rpm","sssd-nfs-idmap-2.9.4-24.oe2403sp3.x86_64.rpm","sssd-proxy-2.9.4-24.oe2403sp3.x86_64.rpm","sssd-tools-2.9.4-24.oe2403sp3.x86_64.rpm","sssd-winbind-idmap-2.9.4-24.oe2403sp3.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3647"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68742"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68744"}],"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}],"database_specific":{"severity":"Medium"}}
