What the CVE records say

CVE-2023-0464 — A security vulnerability has been identified in all supported versions of OpenSSL related to the verification of X.509 certificate chains that include policy constraints. Attackers may be able to exploit this vulnerability by creating a malicious certificate chain that triggers exponential use of computational resources, leading to a denial-of-service (DoS) attack on affected systems. Policy processing is disabled by default but can be enabled by passing the `-policy' argument to the command line utilities or by calling the `X509_VERIFY_PARAM_set1_policies()' function.

Impact

Successful exploitation of this vulnerability could lead to Denial of Service (DoS). <br><br> ONTAP 9 (formerly Clustered Data ONTAP):<br> Affected only when SAML is enabled.

What to do

Check the affected products listed above against the official advisory's affected-versions table — that is where the exact ONTAP 9 release, ONTAP tool, or management product versions are named.
If affected and a fixed release exists, plan the upgrade — see the ONTAP upgrade runbook.
If exploitation is listed as "active", treat remediation as urgent and review exposure (management LIFs, ONTAP S3, SnapMirror endpoints).
Harden in parallel: security hardening baseline and ransomware protection on ONTAP.
