Vulnerability Details CVEID: CVE-2019-6454 DESCRIPTION: systemd is vulnerable to a denial of service, caused by a flaw in the bus_process_object function in bus-objects.c. By sending a specially-crafted DBUS message, a local authenticated attacker could exploit this vulnerability to crash PID 1 and result in a subsequent kernel panic. CVSS Base Score: 5.5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 157193 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H) Affected Products and Versions IBM MQ Advanced CloudPak (IBM Cloud Private, all platforms) Continuous Delivery v2.0.0 - v2.2.2 IBM MQ Advanced CloudPak (IBM Cloud Private on RedHat OpenShift) Continuous Delivery v2.1.0 - v2.2.1 Remediation/Fixes IBM MQ Advanced CloudPak (IBM Cloud Private, all platforms) Continuous Delivery Apply Fix IBM-MQ-Adv-Cloud-Pak-2.2.3 to upgrade to version v2.2.3 IBM MQ Advanced CloudPak (IBM Cloud Private on RedHat OpenShift) Continuous Delivery Apply Fix IBM-MQ-Adv-Cloud-Pak-2.2.2-RHOS to upgrade to version v2.2.2 Workarounds and Mitigations None Reference Complete CVSS v3 Guide On-line Calculator v3 Related Information IBM Secure Engineering Web Portal IBM Product Security Incident Response Blog Support for IBM MQ CloudPak versions The support lifecycle for IBM MQ CloudPaks is tied directly to the support lifecycle of the IBM MQ version that runs within the CloudPak. 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 25 February 2019: Original Version published *The CVSS Environment Score is customer environment specific and will ultimately impact the Overall CVSS Score.
