Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-1010 advisory.

 Corrupted pointer in node::fs::ReadFileUtf8(const FunctionCallbackInfo<Value>& args) when args[0] is a string, resulting in an unrecoverable memory leak on every call. Repeated use can cause unbounded memory growth, leading to a denial of service.

 Improper error handling in async cryptographic operations crashes process

 Improper HTTP header block termination in llhttp which enables request smuggling, allowing attackers to bypass proxy-based access controls and submit unauthorized requests. This vulnerability affects only Node.js 20.x users prior to the llhttp v9 upgrade.

 Info: https://nodejs.org/en/blog/vulnerability/may-2025-security-releases#improper-http-header-block- termination-in-llhttp-cve-2025-23167---medium (CVE-2025-23167)

 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)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'dnf update nodejs20 --releasever 2023.7.20250609' to update your system.
