SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionAn update for ntp is now available for Red Hat Enterprise Linux 6.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
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) :

* 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.
