Here are the details from the Slackware 14.1 ChangeLog:
+--------------------------+
patches/packages/ntp-4.2.6p5-i486-5_slack14.1.txz: Rebuilt.
 All stable versions of NTP remain vulnerable to a remote attack where the
 'ntpdc -c monlist' command can be used to amplify network traffic as part
 of a denial of service attack. By default, Slackware is not vulnerable
 since it includes 'noquery' as a default restriction. However, it is
 vulnerable if this restriction is removed. To help mitigate this flaw,
 'disable monitor' has been added to the default ntp.conf (which will disable
 the monlist command even if other queries are allowed), and the default
 restrictions have been extended to IPv6 as well.
 All users of the NTP daemon should make sure that their ntp.conf contains
 'disable monitor' to prevent misuse of the NTP service. The new ntp.conf
 file will be installed as /etc/ntp.conf.new with a package upgrade, but the
 changes will need to be merged into any existing ntp.conf file by the admin.
