Hmm.. Looking either Ubuntu specific or not poppler/evince related.

Fedora rawhide (or 27) with poppler 0.57 and evince 3.25.91 displays the pictures fine.

Downgrading* to poppler on zesty-updates fixed the issue, looks like it's an Ubuntu specific poppler regression.

*get and install zesty versions and it's fixed
http://mirrors.kernel.org/ubuntu/pool/main/p/poppler/libpoppler-cpp0v5_0.48.0-2ubuntu2.1_amd64.deb http://mirrors.kernel.org/ubuntu/pool/main/p/poppler/libpoppler-glib8_0.48.0-2ubuntu2.1_amd64.deb http://mirrors.kernel.org/ubuntu/pool/main/p/poppler/libpoppler64_0.48.0-2ubuntu2.1_amd64.deb http://mirrors.kernel.org/ubuntu/pool/main/p/poppler/poppler-utils_0.48.0-2ubuntu2.1_amd64.deb

It doesn't seem like Fedora Rawhide has any (new) patches modifying poppler at all: https://src.fedoraproject.org/rpms/poppler/tree/f27

There also doesn't seem to be any relevant patches in the Ubuntu packaging...

Otherwise, I can reproduce.

Status changed to 'Confirmed' because the bug affects multiple users.

Rebuilding with openjpeg enabled fixed it - which is similar to this bug- https://bugs.launchpad.net/ubuntu/+source/poppler/+bug/710412.

I don't understand why this is a regression if it was already disabled...

Looks like enabling openjpeg2 would need an old MIR approved first. Got many negative security reviews in the past.

> I don't understand why this is a regression if it was already disabled...

when not using openjpeg poppler has its own parser, maybe there is a bug in that code, would be worth upstreaming in any case

The internal openjpeg parser has been disabled by default and can be re-enabled by passing --enable-libopenjpeg=unmaintained - I tested this and it fixes this bug.

It is not only unmaintained and not recommended to use but they mention having known security issues with the code (and perhaps no plans to fix*). https://lists.freedesktop.org/archives/poppler/2017-May/012229.html

Adding security team as I'd definitely want their opinion before moving forward.

*It appears at least one likely related CVE was fixed by security team - "fix NULL pointer dereference in JPXStream::readUByte" but not upstreamed.

Even Rouault has been checking in a huge number of fixes for upstream openjpeg, and he's been remarkably responsive to Agostino Sarubbo's fuzzing efforts. I suspect the next time I review the openjpeg codebase I'll find something far more sustainable than the last time around.

Thanks

This bug makes the PDF viewer all but useless in artful. Can we hope to see a bug fix before release?

I don't think poppler is the issue here, I've tested this in artful with: evince 3.24.1-ubuntu2 and libpoppler68 0.57.0-2ubuntu2 and couldn't reproduce this issue. https://imgur.com/a/YyDZD

Right, let's upload a build with --enable-libopenjpeg=unmaintained for this cycle and try to get the external library promoted next cycle

Ok, I could reproduce seems that it has some regression in libpoppler-glib8. If you downgrade only this .deb for (https://launchpad.net/~ubuntu-security/+archive/ubuntu/ppa/+build/13046914/+files/libpoppler-glib8_0.48.0-2ubuntu2.1_amd64.deb) things will works fine.

This bug was fixed in the package poppler - 0.57.0-2ubuntu3

---------------
poppler (0.57.0-2ubuntu3) artful; urgency=medium

  * debian/rules:
    - build with --enable-libopenjpeg=unmaintained which makes the poppler
      openjpeg parser used as it was in Ubuntu until now. Upstream doesn't
      recommend that but the libopenjpeg MIR has still not been approved and
      without a parser some documents are rendered as blank. (lp: #1714596)
