    Summary: Updated ldb packages fix security vulnerability

    Details: Garming Sam reported an out-of-bounds read in the ldb_wildcard_compare() function of ldb, resulting in denial of service (CVE-2019-3824). The ldb package has been updated to version 1.2.4 to fix this issue. The sssd and samba packages have been rebuilt against the updated ldb. 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. (CVE-2019-3811)
