CVE-2019-3811 (GCVE-0-2019-3811)

Vulnerability from cvelistv5 – Published: 2019-01-15 15:00 – Updated: 2025-02-13 16:27

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.

Severity

4.1 (Medium)
