FKIE_CVE-2020-15719

Vulnerability from fkie_nvd - Published: 2020-07-14 14:15 - Updated: 2024-11-21 05:06
Summary
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.
