Vulnerability Details CVEID: CVE-2018-16866 DESCRIPTION: systemd could allow a local attacker to obtain sensitive information, caused by an out-of-bounds read in journald. By sending specially-crafted command arguments, an attacker could exploit this vulnerability to obtain sensitive information. CVSS Base Score: 6.2 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 155360 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) CVEID: CVE-2018-16865 DESCRIPTION: systemd is vulnerable to a denial of service, caused by a memory corruption flaw when calling the alloca function. By sending specially-crafted command arguments, a local attacker could exploit this vulnerability to cause a denial of service. CVSS Base Score: 6.2 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 155359 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) CVEID: CVE-2018-16864 DESCRIPTION: systemd is vulnerable to a denial of service, caused by a memory corruption flaw when calling the syslog function. By sending specially-crafted command arguments, a local attacker could exploit this vulnerability to cause a denial of service.

When the underlying MQ version goes out of support then the CloudPak will automatically go out of support. IBM MQ CloudPaks are only available with Continous Delivery versions of IBM MQ and so follow the IBM MQ Continuous Delivery support lifecycle . The version number for the CloudPak provides an indication to customers on what kind of change has been made between different versions. The versioning system used in CloudPaks is the semver versioning system and does not correlate directly to the V.R.M.F version used by IBM MQ. For reference the table below shows which versions of IBM MQ are available with which version of CloudPak, this can be used to determine whether the version of CloudPak you are using is still in support: IBM MQ CloudPak and IBM MQ versions +---------+---------------------------+---------------------------------------+ | IBM MQ | IBM MQ CloudPak for IBM | IBM MQ CloudPak for IBM Cloud Private | | Version | Cloud Private Version | on RedHat OpenShift Version | +---------+---------------------------+---------------------------------------+ |9.1.1 |2.2.0 and later |2.2.0 and later | +---------+---------------------------+---------------------------------------+ |9.1.0 |2.0.0 -2.1.0 |2.1.0 | +---------+---------------------------+---------------------------------------+ |9.0.5 |1.3.0 |N/A | +---------+---------------------------+---------------------------------------+ |9.0.4 |1.2.0 - 1.2.2 |N/A | +---------+---------------------------+---------------------------------------+ |9.0.3 |1.0.0 - 1.1.0 |N/A | +---------+---------------------------+---------------------------------------+ Change History 8 February 2019: Original Version published 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."
