-------- Forwarded Message -------- Subject: libc6: Permission denied, intermittent in execve Date: Mon, 27 Jul 2020 10:25:27 +0200 From: Alessandro Vesely <ves...@tana.it> To: Devuan Bug Tracking System <sub...@bugs.devuan.org> Dear Maintainer, in certain situations, execve fails setting errno to EACCESS. The same program, launched by the same user in different ways, succeeds or fails according to preceding actions. None of the failure conditions for EACCESS is met. The case at hand happens with an old version of Thunderbird and a LibreOffice attachment. After saving the attachment, Thunderbird execs gio-launch-desktop. The latter tries to exec libreoffice6.4 and fails. I strace'd the full arguments used in the failed execve(), and copied them to a simple C program which runs just that execve() call. When called from the command line, the program succeeds. Then I replaced the gio-launch-desktop executable with my straw men. When called from Thunderbird, the program fails.
