Summary

NTP is used by Power Hardware Management Console (HMC). HMC has addressed the applicable CVEs

Vulnerability Details

CVEID: CVE-2015-7703
DESCRIPTION: Network Time Protocol (NTP) could allow a remote attacker to traverse directories on the system, caused by the failure to enforce local access only of the "pidfile" and "driftfile" configuration directives. An attacker could exploit this vulnerability to view arbitrary files on the system.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/107445 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)

CVEID: CVE-2016-1547
DESCRIPTION: NTP is vulnerable to a denial of service, caused by the demobilization of a preemptable client association. By sending specially crafted crypto NAK packets, an attacker could exploit this vulnerability to cause a denial of service.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/112739 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID: CVE-2016-1548
DESCRIPTION: NTP could allow a remote attacker to bypass security restrictions, caused by an error in the ntpd client. By changing the client from basic client/server mode to interleaved symmetric mode, an attacker could exploit this vulnerability to modify the time of the client or cause a denial of service.
CVSS Base Score: 7.2
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/112740 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:L)

CVEID: CVE-2016-1550
DESCRIPTION: NTP could allow a local attacker to bypass security restrictions, caused by the failure to use a constant-time memory comparison function when validating the authentication digest on incoming packets. By sending a specially crafted packet with an authentication payload, an attacker could exploit this vulnerability to conduct a timing attack to compute the value of the valid authentication digest.
CVSS Base Score: 4
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/112742 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N)

CVEID: CVE-2016-2518
DESCRIPTION: NTP is vulnerable to a denial of service, caused by an error when using a specially crafted packet to create a peer association with hmode > 7. An attacker could exploit this vulnerability to cause the MATCH_ASSOC() function to trigger an out-of-bounds read.
CVSS Base Score: 2
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/112746 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:H/UI:R/S:U/C:N/I:N/A:L)
