The OpenSSL Heartbleed fix for Digi Embedded Yocto 1.4  is available in the github repositories.

The instructions to fetch the Digi Embedded Yocto 1.4.1 update are as follows -

For customers who are deploying Digi Embedded Yocto for the first time, the instructions you should follow are:

                      # mkdir dey-1.4.1

                      # cd dey-1.4.1

                      # repo init -u https://github.com/dgii/dey-manifest.git-b refs/tags/1.4.1

                      # repo sync --no-repo-verify

For customers who *already* have dey-1.4.0 deployed, and want to update the OpenSSL libraries, the instructions are:

                      # cd <path/to/dey-1.4>

                      # repo init -b refs/tags/1.4.1

                      ** Note that in the previous step there is no need to set the URL as it is in the metadata of the previous deployment. **

                      # repo sync  --no-repo-verify
