<p>An update that solves three vulnerabilities can now be installed.</p>
<h2>Description:</h2>
<p>This update for dnsdist fixes the following issues:</p>
<ul>
<li>update to 1.8.0</li>
<li>Implements dnsdist in SLE15 (jsc#PED-3402)</li>
<li>
<p>Security fix: fixes a possible record smugging with a crafted DNS query with trailing data (CVE-2018-14663, bsc#1114511)</p>
</li>
<li>
<p>update to 1.2.0 (bsc#1054799, bsc#1054802)
This release also addresses two security issues of low severity, CVE-2016-7069 and CVE-2017-7557. The first issue can lead to a
denial of service on 32-bit if a backend sends crafted answers,
and the second to an alteration of dnsdist’s ACL if the API is
enabled, writable and an authenticated user is tricked into
visiting a crafted website.</p>
</li>
</ul>
