   An update that fixes three vulnerabilities is now available.

Description:

   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 following non-security issues were fixed:

   * Fix slew mode for leap seconds (bnc#918342).
