Summary: An update for ntp is now available for Red Hat Enterprise Linux 6.7 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Low. 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux HPC Node EUS (v. 6.7) - x86_64 Red Hat Enterprise Linux HPC Node Optional EUS (v. 6.7) - noarch, x86_64 Red Hat Enterprise Linux Server EUS (v. 6.7) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional EUS (v. 6.7) - i386, noarch, ppc64, s390x, x86_64 3. Description: 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): * ntp: Stack-based buffer overflow in ntpq and ntpdc allows denial of service or code execution (CVE-2018-12327) For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 After installing this update, the ntpd daemon will restart automatically. 5.
