CVE-2020-15719

4.2 mediumEPSS 2.5%

Medium (4.2). EPSS 2.5% chance of exploitation in the next 30 days.

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.
