If a user was configured with no home directory set, sssd would return '/' (the root directory) instead of '' (the empty string / no home directory). This could impact services that restrict the user's filesystem access to within their home directory through chroot() etc. All versions before 2.1 are vulnerable.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:H","score":5.2},"cwes":["CWE-200","CWE-552"],"references":["http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00026.html","http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00045.html","http://www.securityfocus.com/bid/106644","https://access.redhat.com/errata/RHSA-2019:2177","https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3811"],"products":["debian:debian_linux","fedoraproject:fedora","fedoraproject:sssd","opensuse:leap","redhat:enterprise_linux"],"source":"nvd","synced_at":"2026-10-19T20:54:36.112582389+00:00"},"epss":{"cve":"CVE-2019-3811","score":0.00696,"percentile":0.53044,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
