SUSE Security Update: Security update for ntp ______________________________________________________________________________
Announcement ID: SUSE-SU-2015:0274-1 Rating: important References: #910764 #911792 Cross-References: CVE-2014-9293 CVE-2014-9294 CVE-2014-9297 CVE-2014-9298 Affected Products: SUSE Linux Enterprise Server 12 SUSE Linux Enterprise Desktop 12 ______________________________________________________________________________
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).
