Debian DSA-3747-1 : exim4 - security update

medium Nessus Plugin ID 96104
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 Debian host is missing a security-related update.

Description

Bjoern Jacke discovered that Exim, Debian's default mail transfer agent, may leak the private DKIM signing key to the log files if specific configuration options are met.

Solution

Upgrade the exim4 packages.

For the stable distribution (jessie), this problem has been fixed in version 4.84.2-2+deb8u2.
