  "title": "sssd-krb5-common: A vulnerability was found in sssd",
  "description": "A vulnerability was found in sssd. If a user was configured with no home directory set, sssd would return \u0027/\u0027 (the root directory) instead of \u0027\u0027 (the empty string / no home directory). This could impact services that restrict the user\u0027s filesystem access to within their home directory through chroot() etc. All versions before 2.1 are vulnerable.",
