Zend-Mail remote code execution in zend-mail via Sendmail adapter
When using the zend-mail component to send email via the `Zend\Mail\Transport\Sendmail` transport, a malicious user may be able to inject arbitrary parameters to the system sendmail program. The attack is performed by providing additional quote characters within an address; when unsanitized, they can be interpreted as additional command line arguments, leading to the vulnerability.
The following example demonstrates injecting additional parameters to the sendmail binary via the From address:
```
use Zend\Mail;
$mail = new Mail\Message();
$mail->setBody('This is the text of the email.');
// inject additional parameters to sendmail command l
The setFrom function in the Sendmail adapter in the zend-mail component before 2.4.11, 2.5.x, 2.6.x, and 2.7.x before 2.7.2, and Zend Framework before 2.4.11 might allow remote attackers to pass extra parameters to the mail command and consequently execute arbitrary code via a \" (backslash double quote) in a crafted e-mail address.
