NVD Description

Note: Versions mentioned in the description apply only to the upstream act package and not the act package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

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.
