<define-tag moreinfo>

<p>It was discovered that there was an XML External Entity (XXE) issue in
libjdom2-java, a library for reading and manipulating XML documents. Attackers
could have caused a denial of service attack via a specially-crafted HTTP
request.</p>

<ul>

<li><a href="https://security-tracker.debian.org/tracker/CVE-2021-33813">CVE-2021-33813</a>

    <p>An XXE issue in SAXBuilder in JDOM through 2.0.6 allows attackers to
    cause a denial of service via a crafted HTTP request.</p></li>

<p>For Debian 9 <q>Stretch</q>, these problems have been fixed in version
2.0.6-1+deb9u1.</p>

<p>We recommend that you upgrade your libjdom2-java packages.</p>
