TLDR: The new updates are 1.8.0_361 (aka 8u361), 11.0.18, 17.0.6, and 19.0.2 respectively). For more on each of them, including what changed and the security fixes they each contain (including their CVE scores regarding urgency of concerns), see the Oracle resources I list below. Oracle calls them "critical patch updates" (yep, CPU), but they are in fact scheduled quarterly updates, so that "critical" nomenclature may be a bit overstated. And as is generally the case with these Java updates, most of them have the same changes and fixes as each other, though not always.

Update: After posting this, I learned of some rather surprising implications of a new feature of the new JDK installer, as 11.0.18 or 17.0.6 and later. For more, see another post I created.

For some folks, that's all they need to hear. For others, read on for topics like:

• Finding more info on these Jan 2023 Java updates
• What about other JVM distributions besides Oracle?
• News for my CF audience (getting the Java updates from Adobe or Oracle, how to update, why you should NOT for now use Java 17 with CF, etc)
• Should you apply the update? how soon?
• Beware a change in the Oct 22 JVM update regarding Java no longer trusting jars signed with SHA-1
• Beware a change in the April 2021 JVM update, if you may be skipping over it
• Wrapping up, getting more help
