| |
| Changes since the last public release (1.4.21): |
| Added PNGMINUS_UNUSED macro to contrib/pngminus/p*.c and added missing |
| parenthesis in contrib/pngminus/pnm2png.c (bug report by Christian Hesse). |
| Compute a larger limit on IDAT because some applications write a deflate |
| buffer for each row (Bug report by Andrew Church). |
| Fixed incorrect typecast of some arguments to png_malloc() and |
| png_calloc() that were png_uint_32 instead of png_alloc_size_t |
| (Bug report by "irwir" in Github libpng issue #175). |
| Initialize memory allocated by png_inflate to zero, using memset, to |
| stop an oss-fuzz "use of uninitialized value" detection in png_set_text_2() |
| due to truncated iTXt or zTXt chunk. |
