            Bug ID: 122192
           Summary: Converting docx in headless mode hangs
           Product: LibreOffice
           Version: 5.3 all versions
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: LibreOffice
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: rb at awave.com

Description:
My application runs on a Ubuntu 16.04 web server where uploaded files
automatically get's converted to PDF with doc2pdf which is part of unoconv
which again uses Libreoffice in headless mode. When trying to convert the
corrupted DOCX document hangs with 100% of the CPU utilized and eventually I
have to reboot to recover.

Steps to Reproduce:
1. Have a Word document (DOCX) that is corrupted
2. Try to convert it to PDF: libreoffice --headless --convert-to pdf
broken.docx
3. Trying with a Word document that is not corrupted works fine

Actual Results:
When trying to convert the corrupted DOCX document hangs with 100% of the CPU
utilized and eventually I have to reboot to recover:

javaldx: Could not find a Java Runtime Environment!
Warning: failed to read path from javaldx
W: Unknown node under /registry/extlang: deprecated
W: Unknown node under /registry/grandfathered: comments
W: Unknown node under /registry/grandfathered: comments
Fontconfig warning: ignoring UTF-8: not a valid region tag
convert /home/forge/broken.docx -> /home/forge/broken.pdf using filter :
writer_pdf_Export

Expected Results:
Command exits to shell with an error.


Reproducible: Always


User Profile Reset: No



Additional Info:
I would suggest one of these things would happen:

1. Command exits with an error
2. Set a timeout and if reached, the command
3. Be able to detect if DOCX document is broken

Unfortunately I cannot provide you with the broken Word document because it
contains sensitive information. Trying to censor the sensitive information
would require me to create an new document that is not corrupted.
