The remote SUSE host is missing one or more security updates.
ntp was updated to fix two security related flaws as well as 'slew' mode handling for leap seconds. The following vulnerabilities were fixe : - ntpd could accept unauthenticated packets with symmetric key crypto. (CVE-2015-1798) - ntpd authentication did not protect symmetric associations against DoS attacks (CVE-2015-1799) - ntp-keygen may generate non-random symmetric keys on big-endian systems (bsc#928321, CVE-2015-3405). The update package also includes non-security fixes. See advisory for details. 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.
