<define-tag description>LTS security update</define-tag>
<define-tag moreinfo>
<p>It was discovered that there was an escaping issue in
<tt>libphp-phpmailer</tt>, an email generation utility class for the PHP
programming language.</p>
<p>The <tt>Content-Type</tt> and <tt>Content-Disposition</tt> headers could have
permitted file attachments that bypassed attachment filters which
match on filename extensions. For more information, please see the
<a href="https://github.com/PHPMailer/PHPMailer/security/advisories/GHSA-f7hx-fqxw-rvvj">upstream announcement</a></p>
<ul>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2020-13625">CVE-2020-13625</a>
<p>PHPMailer before 6.1.6 contains an output escaping bug when the name of
a file attachment contains a double quote character. This can result in the
file type being misinterpreted by the receiver or any mail relay processing
the message.</p></li>
</ul>
<p>For Debian 8 <q>Jessie</q>, these problems have been fixed in version
5.2.9+dfsg-2+deb8u6.</p>
<p>We recommend that you upgrade your libphp-phpmailer packages.</p>

these updates to your system and frequently asked questions can be
