Debian DLA-762-1 : exim4 security update

medium Nessus Plugin ID 96097

Language:

Synopsis

The remote Debian host is missing a security 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.

For Debian 7 'Wheezy', these problems have been fixed in version 4.80-7+deb7u4.

We recommend that you upgrade your exim4 packages.

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

Solution

Upgrade the affected packages.
