fedora
Calendar Grey September 7, 2023
Dist Fedora Esm H88
A slight security patch for php-phpmailer6 in Fedora 37 has been rolled out, tackling an XSS vulnerability associated with malformed DSN error notifications.
Minor security note * The DSN support added in 6.8.0 reflects the DSN back to the user in an error message if it is invalid

PHPMailer - A full-featured email creation and transfer class for PHP

Class Features

* Probably the world's most popular code for sending email from PHP!

* Used by many open-source projects:

WordPress, Drupal, 1CRM, SugarCRM, Yii, Joomla! and many more

* Integrated SMTP support - send without a local mail server

* Multipart/alternative emails for mail clients that do not read HTML email

* Add attachments, including inline

* Support for UTF-8 content and 8bit, base64, binary, and quoted-printable

encodings

* Compatible with PHP 5.5 and later

* Namespaced to prevent name clashes

* Much more!

Autoloader: /usr/share/php/PHPMailer/PHPMailer6/autoload.php

Update Information:

Minor security note * The DSN support added in 6.8.0 reflects the DSN back to the user in an error message if it is invalid. If a DSN uses user-supplied input (a very bad idea), it opens a distant possibility of XSS if the host app does not escape output. In an abundance of caution, malformed DSNs are no longer reflected in error messages. Changes * Don't reflect malformed DSNs in error messages to avert any risk of XSS * Improve Simplified Chinese, Sinhalese, and Norwegian translations * Don't use setAccessible in PHP >= 8.1 in tests * Avoid a deprecation notice in PHP 8.3 * Fix link in readme
