Hello,
I am not completely sure if this is the right mailing list for asking this question, but since the x11-users list seems to be broken (you cannot register as a subscriber (results in a "We're sorry, we hit a bug!"-Error)
Can you point me to the link you are using? I can file a ticket to look into it.
, nor seem incoming messages to be processed (I sent this question to that list before in early February)), I am gonna ask it here:
There are messages on the list from February.
The last version of XQuartz available for download is from 2016.
Yeah, that's the last time I had any free time to package everything up into a release, and nobody has stepped up to take that over. If you want the latest versions, I suggest using MacPorts to install it.
Is XQuartz immune to all of them or must installing XQuartz be considered as a security issue?
I'm not aware of any that I'd consider extremely alarming. Most of the vulnerabilities that I recall were around privilege escalation to root because Xorg runs as root on other platforms. Since the server runs as the user on macOS, that's not as big a concern.
