Synopsis
The remote Amazon Linux 2023 host is missing a security update.Description
It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1484 advisory.A vulnerability was found in juliangruber brace-expansion up to 1.1.11/2.0.1/3.0.0/4.0.0. It has been rated as problematic. Affected by this issue is the function expand of the file index.js. The manipulation leads to inefficient regular expression complexity. The attack may be launched remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. Upgrading to version 1.1.12, 2.0.2, 3.0.1 and 4.0.1 is able to address this issue.
The name of the patch is a5b98a4f30d7813266b221435e1eaaf25a1b0ac5. It is recommended to upgrade the affected component. (CVE-2025-5889)
node-tar is a full-featured Tar for Node.js. When using default options in versions 7.5.7 and below, an attacker-controlled archive can create a hardlink inside the extraction directory that points to a file outside the extraction root, enabling arbitrary file read and write as the extracting user. Severity is high because the primitive bypasses path protections and turns archive extraction into a direct filesystem access primitive. This issue has been fixed in version 7.5.8. (CVE-2026-26960)
node-tar is a full-featured Tar for Node.js. Prior to version 7.5.10, tar can be tricked into creating a hardlink that points outside the extraction directory by using a drive-relative link target such as C:../target.txt, which enables file overwrite outside cwd during normal tar.x() extraction. This issue has been patched in version 7.5.10. (CVE-2026-29786)
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 2023.10.20260325' or or 'dnf update --advisory ALAS2023-2026-1484 --releasever 2023.10.20260325' to update your system.See Also
