[slackware-security]  ntp (SSA:2018-229-01)

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


Here are the details from the Slackware 14.2 ChangeLog:
+--------------------------+
patches/packages/ntp-4.2.8p12-i586-1_slack14.2.txz:  Upgraded.
  This release improves on one security fix in ntpd:
    LOW/MEDIUM: Sec 3012: Sybil vulnerability: ephemeral association attack
    While fixed in ntp-4.2.8p7 and with significant additional protections for
    this issue in 4.2.8p11, ntp-4.2.8p12 includes a fix for an edge case in
    the new noepeer support. Originally reported by Matt Van Gundy of Cisco.
    Edge-case hole reported by Martin Burnicki of Meinberg.
  And fixes another security issue in ntpq and ntpdc:
    LOW: Sec 3505: The openhost() function used during command-line hostname
    processing by ntpq and ntpdc can write beyond its buffer limit, which
    could allow  an attacker to achieve code execution or escalate to higher
    privileges via a long string as the argument for an IPv4 or IPv6
    command-line parameter. NOTE: It is unclear whether there are any common
    situations in which ntpq or ntpdc is used with a command line from an
    untrusted source. Reported by Fakhri Zulkifli.
