   An update that fixes four vulnerabilities is now available.

Description:

   ntp was updated to fix four security issues.

   These security issues were fixed:
   - CVE-2014-9294: util/ntp-keygen.c in ntp-keygen used a weak RNG seed,
     which made it easier for remote attackers to defeat cryptographic
     protection mechanisms via a brute-force attack (bnc#910764 911792).
   - CVE-2014-9293: The config_auth function in ntpd, when an auth key was
     not configured, improperly generated a key, which made it easier for
     remote attackers to defeat cryptographic protection mechanisms via a
     brute-force attack (bnc#910764 911792).
   - CVE-2014-9298: ::1 can be spoofed on some OSes, so ACLs based on IPv6
     ::1 addresses could be bypassed (bnc#911792).
   - CVE-2014-9297: Information leak by not properly checking a length in
     several places in ntp_crypto.c (bnc#911792).
