Security Bulletin: Vulnerabilities in ntp affect Power Hardware Management Console (CVE-2015-5300, CVE-2015-7704, CVE-2015-8138)

Summary

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

Vulnerability Details

CVEID: CVE-2015-5300**
DESCRIPTION:** Network Time Protocol (NTP) could allow a remote attacker to bypass security restrictions, caused by the failure to correctly implement the threshold limitation for the ‘-g’ option. An attacker could exploit this vulnerability using man-in-the-middle techniques to intercept NTP traffic and make multiple steps larger than the panic threshold.
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/107594 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N)

CVEID: CVE-2015-7704**
DESCRIPTION:** Network Time Protocol (NTP) is vulnerable to a denial of service, caused by an error in the rate-limiting mechanism. By sending spoofed Kiss-o’-Death packets, an attacker could exploit this vulnerability to disable NTP at a victim client.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/107446 for the current score
CVSS Environmental Score*: Undefined

CVEID: CVE-2015-8138**
DESCRIPTION:** NTP could allow a remote attacker to bypass security restrictions. By sending a specially crafted packet with an origin timestamp of zero, an attacker could exploit this vulnerability to bypass the timestamp validation check.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/110025 for the current score
CVSS Environmental Score*: Undefined
