Category:Red Hat Local Security Checks
Title:RedHat Update for ntp RHSA-2017:3071-01
Summary:The remote host is missing an update for the 'ntp'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'ntp'
package(s) announced via the referenced advisory.

Vulnerability Insight:
The Network Time Protocol (NTP) is used
to synchronize a computer's time with another referenced time source. These
packages include the ntpd service which continuously adjusts system time and
utilities used to query and configure the ntpd service.

Security Fix(es):

* Two vulnerabilities were discovered in the NTP server's parsing of
configuration directives. A remote, authenticated attacker could cause ntpd
to crash by sending a crafted message. (CVE-2017-6463, CVE-2017-6464)

* A vulnerability was found in NTP, in the parsing of packets from the
/dev/datum device. A malicious device could send crafted messages, causing
ntpd to crash. (CVE-2017-6462)

Red Hat would like to thank the NTP project for reporting these issues.
Upstream acknowledges Cure53 as the original reporter of these issues.

Affected Software/OS:
