Critical PHPMailer Security Update 5.2.20

[AndrewT]

All versions of PHPMailer prior to 5.2.20 are vulnerable to remote code execution and should be updated immediately. Even if you don't use this library directly, many 3rd party scripts do include it. Please make sure that all of your scripts, especially plugins, are updated and kept as such. Updated PHPMailer releases can be downloaded here.
