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.
For the detailed security status of libphp-phpmailer please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/libphp-phpmailer
