[PATCH] pinentry-emacs: fix timeout race in read_from_emacs (CWE-362)

[NIIBE Yutaka]

Hello,

Thank you for your report.  pinentry-emacs is deprecated, it only
existed in the pinentry source code repository until recently.  It has
been removed already from the repository.

pinentry-emacs is for GnuPG 2.0 or older (with Emacs 25 or older).  I
wonder the reason why openEuler 20.03 includes pinentry-emacs.  Which
version of Emacs it has?  Are you (or any users) using it?  And in what
situation?  If any users with openEuler, I would suggest to build your
pinentry-emacs with the patch.
