From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

So if I'm reading this correctly, three of them have already been patched and the other has also been patched, but has an optional config flag you must enable to enable the patch and fix the security vulnerability?
My understanding is that all issues are patched in the mentioned releases, the config flag is not needed for that.
The config flag has been added because supporting clients with different endianness is undertested and most people will never use it. So if it is going to generate vulnerabilities, it makes sense to be able to disable it easily, and to disable it by default on next major release. Indeed XWayland had it disabled by default already, so only the fourth issue (
ProcRenderAddGlyphs) is relevant there if that default is not changed.Thank you for the clarification.
