"According to the version of the openldap packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerability :
- libldap in certain third-party OpenLDAP packages has a
certificate-validation flaw when the third-party
package is asserting RFC6125 support. It considers CN
even when there is a non-matching subjectAltName (SAN).
This is fixed in, for example, openldap-2.4.46-10.el8
in Red Hat Enterprise Linux.(CVE-2020-15719)
