Detail

Synopsis

Multiple vulnerabilities have been found in BusyBox, the worst of which allows remote attackers to execute arbitrary code.

Background

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

Description

Multiple vulnerabilities have been discovered in BusyBox. Please review the CVE identifiers referenced below for details.

Impact

A remote attacker could possibly execute arbitrary code with the privileges of the process, or cause a Denial of Service condition.

Workaround

There is no known workaround at this time. However, on Gentoo, the remote code execution vulnerability can be avoided if you don't use BusyBox's udhcpc or build the package without the "ipv6" USE flag enabled.

Resolution

All BusyBox users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-apps/busybox-1.24.2"
