          Priority: medium
            Bug ID: 72755
          Assignee: libreoffice-bugs@lists.freedesktop.org
           Summary: LibreOffice refuses to start without exec rights on ~
                    and /tmp
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: henn...@orgizm.net
          Hardware: x86-64 (AMD64)
            Status: UNCONFIRMED
           Version: 4.1.3.2 release
         Component: Libreoffice
           Product: LibreOffice

Problem description:

I'm running Linux with the grsecurity patchset, which can prevent programs or
scripts from starting, if they are in a world-writable directory or in one not
owned by root.

When I start LibreOffice (for example with "libreoffice" from the terminal), it
tries to run "$HOME/.execoooyiXWrf" and afterwards (as a failsave?)
"/tmp/.execooouzDaC0". This is prevented and LibreOffice fails with:

The application can not be started.
Extension Manager: exception in synchronize

Is it necessary, LibreOffice executes those temporary scripts or binaries? Can
it be deactivated somehow?


Steps to reproduce:

1. Start a grsecurity enabled kernel.
2. Ensure "Trusted Path Execution" is enabled for your user.
3. Run "libreoffice" from the terminal.


Platform:

* LibreOffice 4.1.3
* Linux 3.12.5
* grsecurity 3.0, 201312151212
* Arch Linux
