Please ensure that you follow the steps described in "Workarounds and Mitigations" to apply the update.

Latest IBM SAN Volume Controller Code
Latest IBM Storwize V7000 Code
Latest IBM Storwize V5000 and V5100 Code
Latest IBM Storwize V5000E Code
Latest IBM FlashSystem V9000 Code
Latest IBM FlashSystem 9500 Code
Latest IBM FlashSystem 9100 Family Code
Latest IBM FlashSystem 9200 Code
Latest IBM FlashSystem 7300 Code
Latest IBM FlashSystem 7200 Code
Latest IBM FlashSystem 5000 and 5200 Code
Latest IBM Spectrum Virtualize Software
Latest IBM Spectrum Virtualize for Public Cloud

Workarounds and Mitigations

Until you have applied the fix, a temporary alternative is available:

Do not use the "Obtain the package directly" feature in the GUI (available in 8.5.4 and above) or the satask downloadsoftware command on the CLI.
Navigate to the Fix Central website in a separate browser window, download the update package and then upload it in the GUI using the "Provide the package manually" option in the Update System panel (or simply "Update System" prior to 8.5.4).

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.
