Synopsis
========

A vulnerability in BusyBox might allow remote attackers to cause a
Denial of Service condition.

Background
==========

BusyBox is a set of tools for embedded systems and is a replacement for
GNU Coreutils.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 sys-apps/busybox < 1.25.1 >= 1.25.1

Description
===========

The recv_and_process_client_pkt function in networking/ntpd.c in
BusyBox allows remote attackers to cause a Denial of Service (CPU and
bandwidth consumption) via a forged NTP packet, which triggers a
communication loop.

Impact
======

A remote attacker might send a specially crafted package to a machine
running BusyBox ntpd, possibly resulting in a Denial of Service
condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All BusyBox users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-apps/busybox-1.25.1"

References
==========
