   An update that fixes four vulnerabilities is now available.

Description:


   ntp has been updated to fix four security issues:

       * CVE-2014-9294: ntp-keygen used a weak RNG seed, which made it easier
         for remote attackers to defeat cryptographic protection mechanisms
         via a brute-force attack. (bsc#910764)
       * CVE-2014-9293: The config_auth function, when an auth key is not
         configured, improperly generated a key, which made it easier for
         remote attackers to defeat cryptographic protection mechanisms via a
         brute-force attack. (bsc#910764)
       * CVE-2014-9298: ::1 can be spoofed on some operating systems, so ACLs
         based on IPv6 ::1 addresses could be bypassed. (bsc#910764)
       * CVE-2014-9297: vallen is not validated in several places in
         ntp_crypto.c, leading to potential information leak. (bsc#910764)

   Security Issues:

       * CVE-2014-9294
