<background>
<p>BusyBox is a set of tools for embedded systems and is a replacement for
GNU Coreutils.
</p>
</background>
<description>
<p>Multiple vulnerabilities have been discovered in BusyBox. Please review
the CVE identifiers referenced below for details.
</p>
</description>
<impact type="normal">
<p>A remote attacker could possibly execute arbitrary code with the
privileges of the process, or cause a Denial of Service condition.
</p>
</impact>
<workaround>
<p>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.
</p>
</workaround>
<resolution>
<p>All BusyBox users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-apps/busybox-1.24.2"
</code>
</resolution>
