Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It was discovered that there was an escaping issue in libphp-phpmailer, an email generation utility class for the PHP programming language.

The `Content-Type` and `Content-Disposition` headers could have permitted file attachments that bypassed attachment filters which match on filename extensions.

For Debian 9 stretch, this problem has been fixed in version 5.2.14+dfsg-2.3+deb9u2.

We recommend that you upgrade your libphp-phpmailer packages.
