Amazon Linux 2023 : nodejs24, nodejs24-devel, nodejs24-full-i18n (ALAS2023-2026-1609)
critical Nessus Plugin ID 311307
Synopsis
The remote Amazon Linux 2023 host is missing a security update.Description
It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1609 advisory.@isaacs/brace-expansion is a hybrid CJS/ESM TypeScript fork of brace-expansion. Prior to version 5.0.1, @isaacs/brace-expansion is vulnerable to a denial of service (DoS) issue caused by unbounded brace range expansion. When an attacker provides a pattern containing repeated numeric brace ranges, the library attempts to eagerly generate every possible combination synchronously. Because the expansion grows exponentially, even a small input can consume excessive CPU and memory and may crash the Node.js process.
This issue has been patched in version 5.0.1. (CVE-2026-25547)
A flaw was found in zlib. An attacker providing specially crafted input to the crc32_combine64 or crc32_combine_gen64 functions could trigger an infinite loop within the x2nmodp function. This leads to excessive CPU consumption, which can result in a Denial of Service (DoS) for the affected system.
(CVE-2026-27171)
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 nodejs24 --releasever 2023.11.20260427' or or 'dnf update --advisory ALAS2023-2026-1609 --releasever 2023.11.20260427' to update your system.See Also
