Question/Request

The latest build of image-tag php:zts-alpine on docker-hub was push at 27 Sep 2024.

• Is the image build regularly? (automatically or on request?)
• By doing the next tag-update, the latest version of curl will included in the next (and the issue here is fixed by than?)

It is rebuilt periodically, typically as a result of base image updates and PHP version bumps. Unfortunately, the Alpine base image doesn't update as often as it sometimes needs to, so this results in a bit of lag at the higher levels.

In regards to the CVE, is "OCSP stapling" a feature of libcurl that's commonly used in PHP projects? I don't think I've seen it used much, but that could be my sampling bias.
