            Bug ID: 111461
           Summary: XLSX hangs libreoffice and produce a lot of temp files
           Product: LibreOffice
           Version: 5.3.5.2 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: critical
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: damien.chambe at gmail.com

Description:
This hang.XLSX produced by MS Office (unknown version as it has been sent by a
customer by mail) hangs LibreOffice.
In /tmp, a folder is created lu188442iogk4.tmp with a lot of file such as
lu188442ioglh.tmp . At least 6 gb are produced. (after that my disk was full )

Opening with WPS Office, I have detected a hundred of images inserted in the
first sheet, near cell O4, with either a 0px height or a 0px width. If I delete
those images, the file is correctly opened by LibreOffice, see the other file
clean.xlsx


Version: 5.4.0.3
Build ID: 1:5.4.0~rc3-0ubuntu0.16.04.1~lo1
Threads CPU : 4; OS : Linux 4.10; UI Render : par défaut; VCL : gtk3; 
Locale : fr-FR (fr_FR.UTF-8); Calc: CL

And reproduced on another ubuntu installation with Libroffice 5.3.5 on
linux/ubuntu

Steps to Reproduce:
1. Open hang.XLSX
2. Watch for a folder created in tmp folder, a lot of tmp files are created ( >
6gb for a 210 kb worksheet file )
3.

Actual Results:  
LibreOffice hangs and will probability fill your disk with tmp files. This
could prevent the OS to boot normally. Some tmp files are pictures, other are
unknown binary content.

Expected Results:
Open the file, or at least warn the user that is can't fully open the document


Reproducible: Always
