Detail

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.

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"
