• IBM i PTF Guide, Volume 24, Number 6

  Hey, guess what? There are no new Security Bulletins this week (at least as of when we are going to press) and there are no new known security vulnerabilities for any part of the software stack of the IBM i platform. We doubt very much that Windows Server can ever say the same thing, and even Linux, which is the only volume operating system that matters, usually has something going on because, like IBM i and Windows Server, it is more than a kernel but a complete set of thousands of programs and tens of millions of lines of code. …

  Another week, another security vulnerability. This time, there is one in the Db2 stack for IBM i. Specifically, we present to you Security Bulletin: IBM Db2 Mirror for i is vulnerable to denial of service due to gson 217225, which you can read in full at this link.

  A new Oracle JCE Code Signing CA was recently implemented in the IBM JDK to resolve APAR IJ26310. Specifically, this is related to IBM JDK 8.0 SR6 FP25, JDK 7.1 SR4 FP75, and JDK 7.0 SR10 FP75, whereby Java applications running on the IBM i operating system might encounter the error messages “JCE is not installed properly” or “JCE cannot authenticate the provider XX” or “xyz.jar is not signed by a trusted signer” after upgrading to the following IBM i Java Group PTF level or newer.

  The following IBM i Java Group PTF levels install 8.0 SR6 FP25.

• Some Good Advice About Log4j Mitigation Gotchas

  January 24, 2022 Timothy Prickett Morgan

  The Apache Log4j logging utility written in Java and available since the end of the Dot Com Boom in early 2001, has been installed far and wide into many systems and systems software packages in the more than two decades it has been available. And that is why the zero-day security vulnerability discovered by Chinese computing giant Alibaba on November 24 last year and revealed on December 9 has caused so much concern.

  Log4j is everywhere and that means the Log4Shell vulnerability that Alibaba described makes it particularly scary. But before we get into some of the mitigation advice that …

  It is a fairly light week for PTF patches for the IBM i platform, so we are going to go off the board a little bit here in the IBM i PTF Guide this week. Winter is coming and while plenty of us love this season, or all four of them, some of us are not happy when the snow flies.

  Well, after watching this video here, which you should do when you actually have 18 minutes and 49 seconds to really pay attention, you will never look at snowflakes quite the same way again. An amazing hobby from …

  Here is to hoping that all of you enjoyed the Halloween weekend, which is the unofficial beginning of the holiday season here in the United States at least. Mercifully, this has been a quiet week on the PTF front. Don’t get used to it. The situation never stays this way for very long.
