Upstream changes:
WordPress 4.9.7 is now available. This is a security and maintenance release for all versions since WordPress 3.7. We strongly encourage you to update your sites immediately.
WordPress versions 4.9.6 and earlier are affected by a media issue that could potentially allow a user with certain capabilities to attempt to delete files outside the uploads directory.
Thank you to Slavco for reporting the original issue and Matt Barry for reporting related issues.
Seventeen other bugs were fixed in WordPress 4.9.7. Particularly of note were:
Taxonomy: Improve cache handling for term queries.
Posts, Post Types: Clear post password cookie when logging out.
Widgets: Allow basic HTML tags in sidebar descriptions on Widgets admin screen.
Community Events Dashboard: Always show the nearest WordCamp if one is coming up, even if there are multiple Meetups happening first.
Privacy: Make sure default privacy policy content does not cause a fatal error when flushing rewrite rules outside of the admin context.
Performing substitutions during post-patch breaks tools such as mkpatches,
making it very difficult to regenerate correct patches after making changes,
and often leading to substituted string replacements being committed.
This maintenance release fixes 28 bugs in 4.9, including fixes for Customizer, media library, error notices, and some security fixes. Twenty Seventeen bundled theme and Hello Dolly bundled plugin have also been updated.
WordPress versions 4.9.4 and earlier are affected by three security issues.

In addition to the security fixes, WordPress 4.2.3 contains fixes for
