Amazon Linux 2 : ecs-init (ALASECS-2024-032)

medium Nessus Plugin ID 187770

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 1.75.0-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2ECS-2024-032 advisory.

The HTTP/1 client does not fully validate the contents of the Host header. A maliciously crafted Host header can inject additional headers or entire requests. With fix, the HTTP/1 client now refuses to send requests containing an invalid Request.Host or Request.URL.Host value. (CVE-2023-29406)

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.
