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's NFS idmap plugin. When retrieving cached user or group names, the plugin detects if an entry exceeds the destination buffer size but fails to abort before copying data. A local attacker can trigger this vulnerability by requesting identity lookups that resolve to oversized cached entries, resulting in an out-of-bounds write. This flaw primarily leads to a Denial of Service (DoS) by crashing the identity mapping service, and may also corrupt adjacent process memory.(CVE-2026-104036)","affected":[{"package":{"ecosystem":"openEuler:22.03-LTS-SP4","name":"sssd","purl":"pkg:rpm/openEuler/sssd&distro=openEuler-22.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.6.1-34.oe2203sp4"}]}],"ecosystem_specific":{"aarch64":["python3-sssd-2.6.1-34.oe2203sp4.aarch64.rpm","sssd-2.6.1-34.oe2203sp4.aarch64.rpm","sssd-debuginfo-2.6.1-34.oe2203sp4.aarch64.rpm","sssd-debugsource-2.6.1-34.oe2203sp4.aarch64.rpm","sssd-devel-2.6.1-34.oe2203sp4.aarch64.rpm"],"noarch":["sssd-help-2.6.1-34.oe2203sp4.noarch.rpm"],"src":["sssd-2.6.1-34.oe2203sp4.src.rpm"],"x86_64":["python3-sssd-2.6.1-34.oe2203sp4.x86_64.rpm","sssd-2.6.1-34.oe2203sp4.x86_64.rpm","sssd-debuginfo-2.6.1-34.oe2203sp4.x86_64.rpm","sssd-debugsource-2.6.1-34.oe2203sp4.x86_64.rpm","sssd-devel-2.6.1-34.oe2203sp4.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-4425"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-104036"}],"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:H"}],"database_specific":{"severity":"Medium"}}
