libpng 1.6.47 - February 18, 2025 ================================= This is a public release of libpng, intended for use in production code. Files available for download ---------------------------- Source files with LF line endings (for Unix/Linux): * libpng-1.6.47.tar.xz (LZMA-compressed, recommended) * libpng-1.6.47.tar.gz (deflate-compressed) Source files with CRLF line endings (for Windows): * lpng1647.7z (LZMA-compressed, recommended) * lpng1647.zip (deflate-compressed) Other information: * README.md * LICENSE.md * AUTHORS.md * TRADEMARK.md Changes from version 1.6.46 to version 1.6.47 --------------------------------------------- * Modified the behaviour of colorspace chunks in order to adhere to the new precedence rules formulated in the latest draft of the PNG Specification. (Contributed by John Bowler) * Fixed a latent bug in `png_write_iCCP`. This would have been a read-beyond-end-of-malloc vulnerability, introduced early in the libpng-1.6.0 development, yet (fortunately!) it was inaccessible before the above-mentioned modification of the colorspace precedence rules, due to pre-existing colorspace checks.
