ipsec-tools was updated to fix one security issue and a bug.
This security issue was fixed:
Due to a packaging error, the racoonf.conf config file was symlinked to /usr/share/doc/packages/ipsec-tools/examples/racoon/samples/racoon.conf on some processor platforms, edits might have happened only in this example file.
Before upgrading, please check if /etc/racoon/racoon.conf is a symlink to this example file and backup the content. (bsc#939810)
