Echo: github.com/moby/sys/user: security update to 0.4.1

medium Tenable Self-Hosted Container Security Plugin ID 474120

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - The `github.com/moby/sys/user` package provides Go utilities for parsing and looking up entries in Unix-
 style user and group database files. Versions before 0.4.1 do not sufficiently limit entries when parsing
 `/etc/passwd`- or `/etc/group`-style files, allowing an attacker who can supply a specially crafted file
 to cause excessive memory consumption and potentially terminate the affected process due to an out-of-
 memory condition. This issue is patched in version 0.4.1. As a workaround, avoid parsing attacker-
 controlled user or group database files, or validate and limit untrusted input before parsing it.
 (CVE-2026-61801)

Solution

Update the github.com/moby/sys/user library and its related packages to version 0.4.1 or later.
