Amazon Linux 2 : ecs-init (ALASECS-2025-065)

medium Nessus Plugin ID 238255

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of ecs-init installed on the remote host is prior to 1.94.0-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2ECS-2025-065 advisory.

 The tokenizer incorrectly interprets tags with unquoted attribute values that end with a solidus character (/) as self-closing. When directly using Tokenizer, this can result in such tags incorrectly being marked as self-closing, and when using the Parse functions, this can result in content following such tags as being placed in the wrong scope during DOM construction, but only when tags are in foreign content (e.g.
 <math>, <svg>, etc contexts).

 After analysis, we have determined that 2025-22872 do not pose a security risk to docker or containerd on Amazon Linux 2 or Amazon Linux 2023. Source code analysis using govulncheck has confirmed that these packages do not contain the vulnerable code. As a result, no security patches are required for these specific packages on AL2 and AL2023. (CVE-2025-22872)

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 'yum update ecs-init' to update your system.
