<define-tag description>LTS security update</define-tag>
<define-tag moreinfo>
<p>A security vulnerability was discovered in lucene-solr, an enterprise
search server.</p>
<p>The DataImportHandler, an optional but popular module to pull in data
from databases and other sources, has a feature in which the whole DIH
configuration can come from a request's <q>dataConfig</q> parameter. The
debug mode of the DIH admin screen uses this to allow convenient
debugging / development of a DIH config. Since a DIH config can contain
scripts, this parameter is a security risk. Starting from now on, use
of this parameter requires setting the Java System property
<q>enable.dih.dataConfigParam</q> to true. For example this can be achieved
with solr-tomcat by adding -Denable.dih.dataConfigParam=true to
JAVA_OPTS in /etc/default/tomcat8.</p>
<p>For Debian 9 stretch, this problem has been fixed in version
3.6.2+dfsg-10+deb9u3.</p>
<p>We recommend that you upgrade your lucene-solr packages.</p>
<p>For the detailed security status of lucene-solr please refer to
its security tracker page at:
