> Debian-specific: no

> mailx is a often used by other programs to send email. Unfortunately
> mailx as distributed in Debian GNU/Linux 2.1 has some features that
> made it possible to execute system commands if a user can trick a
> privileged program to send email using /usr/bin/mail. 

> This has been fixed in version 8.1.1-10.1.1slink.2 by no longer
> allowing all configuration options to be set using the environment.

> We recommend you upgrade your mailx package immediately.
