<background>
<p>BIND is the Berkeley Internet Name Domain Server.</p>
</background>
<description>
<p>Multiple vulnerabilities have been discovered in BIND:</p>
<ul>
<li>Domain names are not properly revoked due to an error in the cache
update policy (CVE-2012-1033).
</li>
<li>BIND accepts records with zero-length RDATA fields (CVE-2012-1667).</li>
<li>An assertion failure from the failing-query cache could occur when
DNSSEC validation is enabled (CVE-2012-3817).
</li>
<li>A memory leak may occur under high TCP query loads (CVE-2012-3868).</li>
<li>An assertion error can occur when a query is performed for a record
with RDATA greater than 65535 bytes (CVE-2012-4244).
</li>
</ul>
</description>
<impact type="normal">
<p>A remote attacker may be able to cause a Denial of Service condition or
keep domain names resolvable after it has been deleted from registration.
</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All BIND users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=net-dns/bind-9.9.1_p3"
</code>
</resolution>
