I left a comment on that issue. OpenEXR addressed those vulnerabilities
in version 2.5.4, while we're at 2.5.5.

Looking at the releases page for openexr, it seems that both versions 2
and 3 are being actively maintained. We can have both, and IMO we
should. But there's no need to work on it immediately.

I built the package and executed darktable --version and also see that
openexr support is enabled. This patch LGTM then. I will now wait for a
committer to review.

Thanks,

Vinicius
