ipsec-tools was updated to fix one security issue and a bug. This security issue was fixed: - CVE-2015-4047: racoon/gssapi.c in ipsec-tools allowed remote attackers to cause a denial of service via a series of crafted UDP requests . 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
