I ran openSUSE Leap 42.2 with Apache 2.4.23-8.9.1.
I upgraded to openSUSE Leap 42.3. With this upgrade, I hoped Apache would upgrade to Apache 2.4.26.
Unfortunately it isn't the case. Also after upgrading openSUSE, there are no patches available for Apache.
How to upgrade to Apache 2.4.26?
Managed to update Apache.
I didn’t know that you can choose a version in the Yast patches window.
Under tab “Versions” for apache2 I choose “2.4.27-125.1-x86_64 from openSUSE-Leap-42.3-Apache with priority 99 and vendor…”.
Af some “Conflict Resolution” messages, I finally have an updated webserver.
