If you run a (recent) Linux, and you type `pngcheck` (with no arguments) what version number do you get?

None, command not found

@Kerplunk Thanks, I hd planned to add that option but apparently polls have only four options.
@Kerplunk what distro? And does it make it easy to install it (eg apt-get install pngcheck)?

@svgeesus

Hi Chris,
Thank you for the heads up

Available is pngcheck (4.0.1-1 Debian:unstable [amd64])

sudo apt update && sudo apt install pngcheck

Distro is antiX Debian based.

pngcheck versions 3.0.2 and earlier have a divide-by-zero bug when zlib-decoding interlaced PNGs with extra data beyond what is required for the declared image dimensions.

Will look at usage tomorrow, see what the devs say about inclusion in the distro.

@svgeesus "PNGcheck, version 2.3.0 of 7 July 2007". Downloaded just now to Ubuntu running under Win11.
@bosak Wow that is truly ancient (and more recent versions fix several security issues)
@svgeesus That's what comes in with a fresh install. I could easily believe that the stuff coming from wherever the updates come from for the Windows 11 version of Ubuntu are not of the best quality.

@svgeesus If I had it installed it'd be 3.0.3:

~> apt list pngcheck
pngcheck/questing 3.0.3-3 amd64

@svgeesus Fedora 43 offers to install 4.0.1 after "command not found"
on a Debian 13 server, the package available is 3.0.3

@svgeesus On Fedora 43, not installed by default, available via package repositories:

pngcheck.x86_64 4.0.1-1.fc43 updates
