It is suspected that this package is vulnerable to a security vulnerability via embedded dev-php/PHPMailer. As such we ask maintainers with packages suspected to be vulnerable to verify if the package is (or have been) affected.
Please see the information contained in the tracker bug 603752.
As listed in the Drupal advisory, this vulnerability doesn't affect Core, so it doesn't affect the package provided by Gentoo and only a 3rd party library.
As such, I suggest we close the bug.
Closing as invalid: Package was never affected.
