<description>
<p>Florian Weimer, Todd Sabin, Michal Zalewski et al. discovered further
parsing flaws in Bash. The unaffected Gentoo packages listed in this GLSA
contain the official patches to fix the issues tracked as CVE-2014-6277,
CVE-2014-7186, and CVE-2014-7187. Furthermore, the official patch known
as “function prefix patch” is included which prevents the
exploitation of CVE-2014-6278.

<impact type="high">
<p>A remote attacker could exploit these vulnerabilities to execute
arbitrary commands or cause a Denial of Service condition via various
vectors.

</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>

</code>
<p>All Bash 3.2 users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=app-shells/bash-3.2_p56:3.2"
