vulnerability :
- A vulnerability was found in sssd where, 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().(CVE-2019-3811)
