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).
