Comment 1 Pedro Sampaio 2021-01-27 23:24:46 UTC
Created openldap tracking bugs for this issue:

Affects: fedora-all [bug 1921402]

Comment 3 Todd Cullum 2021-02-02 23:54:23 UTC
Statement:

This flaw does not affect openldap as shipped with Red Hat Enterprise Linux 8 because the slapd server is not shipped. While Red Hat Enterprise Linux 7 does ship the slapd server, this flaw is out of support scope for Red Hat Enterprise Linux 7 and earlier. For more information on support scope, see https://access.redhat.com/support/policy/updates/errata/ .
