Description Adam Mariš 2015-12-07 12:32:41 UTC

A message injection vulnerability was found in php-PHPMailer affecting versions before 5.2.14, caused by line breaks allowed in addresses, which is valid in RFC5322, but allowing such addresses resulted in invalid RFC5321 SMTP commands. These addresses were allowed by the 'pcre8' validator pattern.
