This update for ipsec-tools fixes one issue. This security issue was fixed :

  • CVE-2016-10396: The racoon daemon contained a remotely exploitable computational-complexity attack when parsing and storing ISAKMP fragments that allowed a remote attacker to exhaust computational resources on the remote endpoint by repeatedly sending ISAKMP fragment packets in a particular order (bsc#1047443).

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