Version        : 5.2.14+dfsg-2.3+deb9u2
CVE ID         : CVE-2020-13625
Debian Bug     : 962827

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.
