<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>

<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 ">=net-dns/bind-9.9.1_p3"
|
|
</code>
