Security Bulletin: Multiple Ntp vulnerability affects IBM Identity Security Governance

Description

## Summary There are multiple security vulnerabilities in various components used by IBM Security Identity Governance and Intelligence regarding the Ntp (CVE-2016-7426 CVE-2016-7433 CVE-2016-9310 CVE-2016-9311 CVE-2016-7429 ) ## Vulnerability Details **CVEID:** [_CVE-2016-7426_](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-7426>)** DESCRIPTION:** NTP is vulnerable to a denial of service, caused by the improper handling of invalid server responses. By sending specially crafted packets with spoofed source address, a remote attacker could exploit this vulnerability to a denial of service. CVSS Base Score: 1.6 CVSS Temporal Score: See [_https://exchange.xforce.ibmcloud.com/vulnerabilities/119094_](<https://exchange.xforce.ibmcloud.com/vulnerabilities/119094>) for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:P/AC:H/PR:H/UI:R/S:U/C:N/I:N/A:L) **CVEID:** [_CVE-2016-7433_](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-7433>)** DESCRIPTION:** NTP is vulnerable to a denial of service, caused by the inclusion of the root delay allowing for an incorrect root distance calculation. An attacker could exploit this vulnerability to cause a denial of service. CVSS Base Score: 1.6 CVSS Temporal Score: See [_https://exchange.xforce.ibmcloud.com/vulnerabilities/119095_](<https://exchange.xforce.ibmcloud.com/vulnerabilities/119095>) for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:P/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:L) **CVEID:** [_CVE-2016-9310_](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-9310>)** DESCRIPTION:** NTP is vulnerable to a denial of service, caused by an error in the control mode (mode 6) functionality. By sending specially crafted control mode packets, a remote attacker could exploit this vulnerability to obtain sensitive information and cause the application to crash. CVSS Base Score: 6.5 CVSS Temporal Score: See [_https://exchange.xforce.ibmcloud.com/vulnerabilities/119087_](<https://exchange.xforce.ibmcloud.com/vulnerabilities/119087>) for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L) **CVEID:** [_CVE-2016-9311_](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-9311>)** DESCRIPTION:** NTP is vulnerable to a denial of service, caused by a NULL pointer dereference when trap service has been enabled. By sending specially crafted packets, a remote attacker could exploit this vulnerability to cause the application to crash. CVSS Base Score: 4.4 CVSS Temporal Score: See [_https://exchange.xforce.ibmcloud.com/vulnerabilities/119086_](<https://exchange.xforce.ibmcloud.com/vulnerabilities/119086>) for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:H) **CVEID:** [_CVE-2016-7429_](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-7429>)** DESCRIPTION:** NTP is vulnerable to a denial of service, caused by an attack on interface selection. By sending specially crafted packets with spoofed source address, a physical attacker could exploit this vulnerability to cause a denial of service.

Customers can evaluate the impact of this vulnerability in their environments by accessing the links in the Reference section of this Security Bulletin. ## Disclaimer According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
