eog (Ubuntu image viewer) consumes all memory when opening a tiff file

[Ben Weiner]

The ImageViewer app (/usr/bin/eog) will go into a loop if a TIFF files are opened. Any TIFF file can cause a loop even if less than 1MB in size, so it seems that the program is encountering an internal issue with the TIFF format.

The loop quickly consumes all free memory and locks up the machine (I do not have any swap).

Steps to reproduce:
* open any TIFF file using ImageViewer, the default image file handler.

Thank you for your bug report. Could you add a file example to the bug?

[Ben Weiner (ben-chgta)]

This file is identical in pixel dimensions to one that caused the bug earlier. It is 1-bit with a size of 10332px x 4148px. It is LZW compressed and contains an entirely white image.

*Opening this file with Image Viewer (eog) doesn't trigger the bug* with the resources available on my system now, though it takes a bit of time to appear and requires over 1GB of memory. I will load up more software and see if that affects the outcome, and I will try the one of the files that did trigger it earlier at the current system usage level (I cannot upload that as it's a private scan from a book and sharing it would violate copyright).

[Ben Weiner (ben-chgta)]

OK the original trigger file is OK now and uses a similar amount of memory to load.

I guess it would be more appropriate to say that there's nothing to stop eog loading a file that's impracticably large, and a refinement would be to do a rough calculation of the memory requirement and ask the user to confirm they want to open it.

[Ben Weiner (ben-chgta)]

OK well with more resources in use the behaviour I am getting is that Image Viewer boots, shows a blank window, and then exits. So that's a little bit like my comment #4.

The issue seems similar to https://gitlab.gnome.org/GNOME/gdk-pixbuf/issues/30
