imageinfo fails in Ubuntu 23.04 with a "no such file or directory" error

[Rocko]

imageinfo fails in Ubuntu 23.04 with a "no such file or directory" error, eg:

$ imageinfo --size /usr/share/backgrounds/Lunar-lobster-side_by_Gixo-dark.png
imageinfo: unable to open image `��s��U': No such file or directory @ error/blob.c/OpenBlob/2924.

$ imageinfo --size /usr/share/backgrounds/Copper_Mountain_by_Eduardo_Battaglia.jpg
imageinfo: unable to open image `�=�V': No such file or directory @ error/blob.c/OpenBlob/2924.

The filename it complains is not found seems to be random and changes each time. Under WSL, it fails but just says "unable to open image `': No such file", ie it doesn't show the random text.

I tried to build imageinfo from source (using apt source imageinfo) but after installing the build-deps (sudo apt build-dep imageinfo) and also the extra package required for Magick-config so configure will succeed, it fails to build with the error "imageinfo.c:373:15: error: ‘Image’ has no member named ‘color_profile’":

The problem is actually in libpopt. Installing the package from Ubuntu 22.10 (libpopt0_1.18-3build1_amd64.deb, https://packages.ubuntu.com/kinetic/amd64/libpopt0/download) fixes the problem.

Downgrading popt from 1.19+dfsg-1 to 1.18-3build1 shows that the problem is not in imageinfo but in popt.

Thank you for taking the time to file a bug report.

I did some investigation and noticed that the problem is actually with imageinfo.

From imageinfo.c:

  filename = poptGetArg(poptctxt);
  if (poptGetArg(poptctxt) != NULL) {
    fprintf(stderr, "imageinfo: must specify a single filename\n");
    poptFreeContext(poptctxt);
    exit(2);
  }
  poptFreeContext(poptctxt);
  if (!filename) {
    fprintf(stderr, "imageinfo: must specify a filename\n");
    exit(3);
  }

This excerpt is saving a pointer to the the "filename" string that's found inside "poptctxt", but then it calls "poptFreeContext", which will invoke "free" on that same string.

Is this likely to be fixed before 23.04 comes out? I'd patch it myself, but as I mentioned, the source from the repos fails to build (with the error ‘Image’ has no member named ‘color_profile’).

Below is what I did. Am I doing something wrong?

apt source imageinfo
sudo apt build-dep imageinfo
sudo apt install graphicsmagick-libmagick-dev-compat # Need this as well as the build-deps

cd imageinfo-0.04
./configure
make

...
