SUSE Security Update: Security update for ntp ______________________________________________________________________________
Announcement ID: SUSE-SU-2015:0259-1 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 11 SP3 for VMware SUSE Linux Enterprise Server 11 SP3 SUSE Linux Enterprise Desktop 11 SP3 ______________________________________________________________________________
An update that fixes four vulnerabilities is now available.
Description:
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)
