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_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:20.03-LTS-SP4","name":"sssd","purl":"pkg:rpm/openEuler/sssd&distro=openEuler-20.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.2.2-29.oe2003sp4"}]}],"ecosystem_specific":{"aarch64":["python2-sssd-2.2.2-29.oe2003sp4.aarch64.rpm","python3-sssd-2.2.2-29.oe2003sp4.aarch64.rpm","sssd-2.2.2-29.oe2003sp4.aarch64.rpm","sssd-debuginfo-2.2.2-29.oe2003sp4.aarch64.rpm","sssd-debugsource-2.2.2-29.oe2003sp4.aarch64.rpm","sssd-devel-2.2.2-29.oe2003sp4.aarch64.rpm"],"noarch":["sssd-help-2.2.2-29.oe2003sp4.noarch.rpm"],"src":["sssd-2.2.2-29.oe2003sp4.src.rpm"],"x86_64":["python2-sssd-2.2.2-29.oe2003sp4.x86_64.rpm","python3-sssd-2.2.2-29.oe2003sp4.x86_64.rpm","sssd-2.2.2-29.oe2003sp4.x86_64.rpm","sssd-debuginfo-2.2.2-29.oe2003sp4.x86_64.rpm","sssd-debugsource-2.2.2-29.oe2003sp4.x86_64.rpm","sssd-devel-2.2.2-29.oe2003sp4.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3648"},{"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:L/I:N/A:N"}],"database_specific":{"severity":"Low"}}
