Azure Linux 3.0 Security Update: nodejs / nodejs18 (CVE-2025-47279)

low Nessus Plugin ID 241941

Language:

Synopsis

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

Description

The version of nodejs / nodejs18 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-2025-47279 advisory.

 - Undici is an HTTP/1.1 client for Node.js. Prior to versions 5.29.0, 6.21.2, and 7.5.0, applications that use undici to implement a webhook-like system are vulnerable. If the attacker set up a server with an invalid certificate, and they can force the application to call the webhook repeatedly, then they can cause a memory leak. This has been patched in versions 5.29.0, 6.21.2, and 7.5.0. As a workaound, avoid calling a webhook repeatedly if the webhook fails. (CVE-2025-47279)

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.
