  "title": "github.com/moby/sys/user has a possible DoS via unbounded parsing of user and group database files",
  "description": "The \u0060github.com/moby/sys/user\u0060 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 \u0060/etc/passwd\u0060- or \u0060/etc/group\u0060-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.",
