IBM i PTF Guide, Volume 20, Number 6

Welcome to the latest edition of the IBM i PTF Guide. This week, here is our update on the Spectre/Meltdown (SM) speculative execution security vulnerabilities. First, we have moved our table of fixes to the master spreadsheet for the IBM i PTF Guide because it is just easier to manage. There are now 16 fixes for V7R1, and 9 for each of the other two releases, in addition to the firmware fixes. They are all MFs, which in all likelihood means an IPL is required to apply them. The good news is that nothing has changed in about eight days on these.
In light of the announcement of Power9 processors in IBM i systems and the Technology Refreshes for IBM i V7R2 and V7R3, we think IBM is working on that instead of any further SM updates. We’ll wait and see. The new PTFs do not replace they old, they are “in addition to,” and they don’t show up in any group PTFs as yet.
You can read all about it at this link.
DB2 for IBM i group for V7R3 and V7R2 has been updated with a large number of fixes, mostly dealing with optimization. It is always a good thing to put this group on, usually contains performance improvements, something we can never get enough of. There are no new DB2 group PTFs for V7R1.
There are new HIPER and Security groups for all three supported releases. They have mostly added some of the SM fixes to them, but there are other fixes in there as well. As always, we recommend putting them on. Just a reminder, the Spectre and Meltdown speculative execution security vulnerabilities have been classified by IBM’s Product Security Incident Response Team (PSIRT) as having a “High Severity” level.
