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.

According to the versions of the openldap packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - A NULL pointer dereference was found in OpenLDAP server     and was fixed in openldap 2.4.55, during a request for     renaming RDNs. An unauthenticated attacker could     remotely crash the slapd process by sending a specially     crafted request, causing a Denial of     Service.(CVE-2020-25692)
