Description:
 steps/mail/sendmail.inc in Roundcube before 1.1.7 and 1.2.x before 1.2.3,
 when no SMTP server is configured and the sendmail program is enabled, does
 not properly restrict the use of custom envelope-from addresses on the
 sendmail command line, which allows remote authenticated users to execute
 arbitrary code via a modified HTTP request that sends a crafted e-mail
 message.
