What the CVE records say

CVE-2024-12243 — A flaw was found in GnuTLS, which relies on libtasn1 for ASN.1 data processing. Due to an inefficient algorithm in libtasn1, decoding certain DER-encoded certificate data can take excessive time, leading to increased resource consumption. This flaw allows a remote attacker to send a specially crafted certificate, causing GnuTLS to become unresponsive or slow, resulting in a denial-of-service condition.

Impact

Successful exploitation of this vulnerability could lead to Denial of Service (DoS).

Affected products

Active IQ Unified Manager for VMware vSphere
NetApp HCI Compute Node (Bootstrap OS)
NetApp SolidFire & HCI Management Node
NetApp SolidFire & HCI Storage Node (Element Software)
ONTAP Select Deploy administration utility
ONTAP tools for VMware vSphere 10

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).
