[ANN] Emergency bugfix release: Org mode 9.6.23

[ANN] Emergency bugfix release: Org mode 9.6.23

[Ihor Radchenko]

Dear all,

I just released Org mode 9.6.23 that fixes several critical
vulnerabilities. The release is coordinated with emergency Emacs 29.3
release
(https://lists.gnu.org/archive/html/info-gnu/2024-03/msg00005.html).

Please upgrade your Org mode *and* Emacs ASAP.

The vulnerabilities involve arbitrary Elisp and LaTeX evaluation when
previewing attachments in Emacs or when opening third-party Org files.

The arbitrary Elisp evaluation is fixed by this release.

The fix for LaTeX evaluation requires Emacs 29.3 and will not work for
the earlier Emacs versions. If upgrading Emacs is not viable, as a
workaround, you can set `org-preview-latex-default-process' to 'verbatim
- this will disable LaTeX previews and avoid the vulnerability.

Since a variant of exploit has been published, it is time to add a test 
that might prevent code change re-introducing the most severe vulnerability.

Thanks!
Applied, onto main, after adding another test case with a call to
(org-mode). Just to be sure.
