CVE-2020-15719  (opens in a new tab)
CWE-295  (opens in a new tab)

How to fix?

Upgrade SLES:15.2 openldap2 to version 2.4.46-9.34.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openldap2 package and not the openldap2 package as distributed by SLES. See How to fix? for SLES:15.2 relevant fixed versions and status.

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.
