Azure Linux 3.0 Security Update: cert-manager / helm (CVE-2025-32386)

medium Nessus Plugin ID 241921

Language:

Synopsis

The remote Azure Linux host is missing one or more security updates.

Description

The version of cert-manager / helm installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2025-32386 advisory.

 - Helm is a tool for managing Charts. A chart archive file can be crafted in a manner where it expands to be significantly larger uncompressed than compressed (e.g., >800x difference). When Helm loads this specially crafted chart, memory can be exhausted causing the application to terminate. This issue has been resolved in Helm v3.17.3. (CVE-2025-32386)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
