[slackware-security]  ntp (SSA:2019-067-01)

New ntp packages are available for Slackware 14.0, 14.1, 14.2, and -current to
fix a security issue.

Here are the details from the Slackware 14.2 ChangeLog:
patches/packages/ntp-4.2.8p13-i586-1_slack14.2.txz:  Upgraded.
  This release fixes a bug that allows an attacker with access to an explicitly
  trusted source to send a crafted malicious mode 6 (ntpq) packet that can
  trigger a NULL pointer dereference, crashing ntpd.
  It also provides 17 other bugfixes and 1 other improvement.
  For more information, see:
  (* Security fix *)
