The remote Ubuntu host is missing one or more security-related patches.


It was discovered that Exim incorrectly handled DKIM DNS decoding.
This flaw could allow a remote attacker to execute arbitrary code.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
