Comment 1 Ben Beasley 2025-12-02 19:34:10 UTC

Why was this filed? The pngcheck software is hosted at www.libpng.org and processes PNG files. It otherwise has no connection to libpng. It does not link libpng, it does not bundle libpng, and there is nothing in the spec file or source archive that ought to suggest otherwise.
