Comment 5 Lumír Balhar 2023-11-12 11:03:58 UTC
I'm reopening this bug for the reason provided in the Bodhi update:

Unfortunately, the patch backported from upstream from version 10 to fix the CVE-2023-44271 is not enough for version 9.5 we have in Fedora 38. The problem is that classes in ImageFont module have also `getsize` method which is deprecated in version 9 and removed in version 10 which means that the fix in version 10 is not applied to these methods and they stay vulnerable in this update.

Comment 9 Lumír Balhar 2024-01-29 08:20:59 UTC
As I mentioned earlier, the patch in version 9 is not enough to fix the vulnerability. I'm willing to help fix it.

The patch uses a function which is not backported as a part of the patch:

File "/usr/lib64/python3.11/site-packages/PIL/ImageFont.py", line 483, in getsize
    _string_length_check(text)
    ^^^^^^^^^^^^^^^^^^^^
NameError: name '_string_length_check' is not defined
