Description

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 the oldstable distribution (jessie), this problem has been fixed in version 4.84.2-2+deb8u5.

For the stable distribution (stretch), this problem has been fixed in version 4.89-2+deb9u3.

We recommend that you upgrade your exim4 packages.
