Security update for ntp
SUSE Security Update: Security update for ntp
The NTP time service could have been used for remote denial of service
amplification attacks.
This issue can be fixed by the administrator as we described in our
security advisory SUSE-SA:2014:001:
http://lists.opensuse.org/opensuse-security-announce/2014-01/msg00005.html
and on
http://support.novell.com/security/cve/CVE-2013-5211.html
This update now also replaces the default ntp.conf template to fix this
problem.
Please note that if you have touched or modified ntp.conf yourself, it
will not be automatically fixed, you need to merge the changes manually as
described.
Additionally the following bug has been fixed:
* ntp start script does not update the /var/lib/ntp/etc/localtime file
if /etc/localtime is a symlink (bnc#838458)
Security Issues:
* CVE-2013-5211
