Ubuntu 16.04 LTS / 18.04 LTS : Exim vulnerability (USN-4075-1)

critical Nessus Plugin ID 127096

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-4075-1 advisory.

 Jeremy Harris discovered that Exim incorrectly handled sort expansions. In environments where sort expansions are used, a remote attacker could possibly use this issue to execute arbitrary code as root.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
