+ <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>
