New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

It was found that Exim leaked DKIM signing private keys to the 'mainlog' log file. As a result, an attacker with access to system log files could potentially access these leaked DKIM private keys.

Solution

Run 'yum update exim' to update your system.
