Detail

The Qualys Research Labs reported a flaw in Exim, a mail transport agent. Improper validation of the recipient address in the deliver_message() function may result in the execution of arbitrary commands.

For the stable distribution (stretch), this problem has been fixed in version 4.89-2+deb9u4.

We recommend that you upgrade your exim4 packages.
