Fedora 43: libpng High CVE-2025-66293 Out-of

The libpng package contains a library of functions for creating and manipulating PNG (Portable Network Graphics) image format files. PNG is a bit-mapped graphics format similar to the GIF format. PNG was created to replace the GIF format, since GIF uses a patented data compression algorithm. Libpng should be installed if you need to manipulate PNG format image files. Update Information : Fixed CVE-2025-66293 (high severity): Out-of-bounds read in png_image_read_composite. Fixed the Paeth filter handling in the RISC-V RVV implementation. Improved the performance of the RISC-V RVV implementation.
