"ntp has been updated to fix four security issues :

  - 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-2014-9294)

  - 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-2014-9293)

  - ::1 can be spoofed on some operating systems, so ACLs
    based on IPv6 ::1 addresses could be bypassed.
    (bsc#910764). (CVE-2014-9298)

  - vallen is not validated in several places in
    ntp_crypto.c, leading to potential information leak.
    (bsc#910764). (CVE-2014-9297)"
