NVD Description

Note: Versions mentioned in the description apply only to the upstream libsss_nss_idmap package and not the libsss_nss_idmap package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
