Synopsis

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

Description

It was discovered that the Exim daemon did not correctly handle certain DKIM identities. A remote attacker could send specially crafted email to run arbitrary code as the Exim user.

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.

Solution

Update the affected exim4-daemon-custom, exim4-daemon-heavy and / or exim4-daemon-light packages.
