Amazon Linux 2 : ecs-service-connect-agent (ALASECS-2025-052)

high Nessus Plugin ID 235072

Synopsis

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

Description

The version of ecs-service-connect-agent installed on the remote host is prior to v1.29.12.1-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2ECS-2025-052 advisory.

Envoy is a cloud-native high-performance edge/middle/service proxy. Prior to 1.33.1, 1.32.4, 1.31.6, and 1.30.10, Envoy's ext_proc HTTP filter is at risk of crashing if a local reply is sent to the external server due to the filter's life time issue. A known situation is the failure of a websocket handshake will trigger a local reply leading to the crash of Envoy. This vulnerability is fixed in 1.33.1, 1.32.4, 1.31.6, and 1.30.10. (CVE-2025-30157)

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-service-connect-agent' to update your system.
