medium Nessus Plugin ID 311331

Synopsis

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

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-1616 advisory.

 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)

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

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

Solution

Run 'dnf update nodejs22 --releasever 2023.11.20260427' or or 'dnf update --advisory ALAS2023-2026-1616 --releasever 2023.11.20260427' to update your system.
