It was discovered that in Exim, a mail transport agent, handling an e-mail can cause a heap-based buffer overflow in some situations. An attacker can cause a denial-of-service (DoS) and possibly execute arbitrary code.



For Debian 8 jessie, these problems have been fixed in version 4.84.2-2+deb8u9.

For Debian 9 stretch, these problems have been fixed in version 4.89-2+deb9u9.

We recommend that you upgrade your exim4 packages.
