NVD Description

Note: Versions mentioned in the description apply only to the upstream neuvector-scanner package and not the neuvector-scanner package as distributed by Chainguard. See How to fix? for Chainguard 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.
