Security update for ntp
SUSE Security Update: Security update for ntp
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
* CVE-2014-9293
* CVE-2014-9298
* CVE-2014-9297
