FKIE_CVE-2019-3811

Vulnerability from fkie_nvd - Published: 2019-01-15 15:29 - Updated: 2026-06-17 02:35
Severity
5.2 (Medium) - CVSS:3.1/AV:A/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:H
Summary
A vulnerability was found in sssd. 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.
