Here is an update, Artifex made a press release

listing
some necessary commits, but the list was incomplete.

They also claimed "Artifex Software is pleased to report that the
recently disclosed security vulnerabilities in Ghostscript have been
resolved.", which, even if they were all patched in their git
repository, which they don't seem to all be, would still not really
be true given the lack of an actual release.

Here is a list of relevant commits I'm aware of so far, some issues
are still open with working exploits available. It's my
understanding that no new release is planned until late September,
and vendors need to either ship a git snapshot when all issues are
resolved, or apply patches. I have testcases for each problem, but
I think the bugs will be visible eventually so I'm not posting them
here.

If someone would put a git repo onto GitHub with all the available
patches applied on a branch, I'm sure a bunch of people would be
grateful.
