Out of Memory while requesting a preview for an image exceeding preview_max_dimensions#41346

Description

opened on Dec 18, 2024

Steps to reproduce

  1. Set 'preview_max_dimensions' => '1000x1000'
  2. Upload both attached files to separate folders (to avoid unintentionally requesting previews for both files at the same time)
  3. Try to load the previews for both files
  4. Observe excessive memory usage for test.png, even though both exceed the maximum dimensions and neither preview is actually generated.

Attachments

test.png
test2.png

Expected behaviour

Image dimensions are checked without loading the entire image into memory.

Actual behaviour

Even though the image is not eligible for preview generation, a large amount of memory is consumed. On my instance hosted on a single-board computer, this triggers an oom-kill:

Setting preview_max_filesize_image to a low value is not a solution, because image compression may reduce unreasonably large images to a normal size.
As far as I can tell, this behavior is caused by

core/lib/private/Preview/Image.php

Line 47 in 0401d6a

$image->load($handle);
being called before dimensions are checked. Instead, something like getimagesize() should be used, which is able to check image dimensions without decoding the entire image.
