Package : exim4
Version : 4.80-7+deb7u6
CVE ID : CVE-2018-6789
Debian Bug : 890000

Meh Chang discovered a buffer overflow flaw in a utility function used
in the SMTP listener of Exim, a mail transport agent. A remote attacker
can take advantage of this flaw to cause a denial of service, or
potentially the execution of arbitrary code via a specially crafted
message.

For Debian 7 "Wheezy", this problem has been fixed in version
4.80-7+deb7u6.

We recommend that you upgrade your exim4 packages.
