[slackware-security]  ntp (SSA:2020-175-01)

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-4.2.8p15-i586-1_slack14.2.txz:  Upgraded.
  This release fixes one vulnerability: Associations that use CMAC
  authentication between ntpd from versions 4.2.8p11/4.3.97 and
  4.2.8p14/4.3.100 will leak a small amount of memory for each packet.
  Eventually, ntpd will run out of memory and abort.
  (* Security fix *)
