MEDIUM 4.2EPSS 2.51%
Does this matter?
Lower severity and a low EPSS score (2.51%). Track it; it rarely justifies an emergency change on its own.
Description
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.
