| Changes since the last public release (1.6.22): |
| |
| Stop a potential memory leak in png_set_tRNS() (Bug report by Ted Ying). |
| Fixed the progressive reader to handle empty first IDAT chunk properly |
| (patch by Timothy Nikkel). This bug was introduced in libpng-1.6.0 and |
| only affected the libpng16 branch. |
| Added tests in pngvalid.c to check zero-length IDAT chunks in various |
| positions. Fixed the sequential reader to handle these more robustly |
| (John Bowler). |
| Corrected progressive read input buffer in pngvalid.c. The previous version |
| the code invariably passed just one byte at a time to libpng. The intent |
| was to pass a random number of bytes in the range 0..511. |
| Moved sse2 prototype from pngpriv.h to contrib/intel/intel_sse.patch. |
| Added missing ")" in pngerror.c (Matt Sarrett). |
| Fixed undefined behavior in png_push_save_buffer(). Do not call |
| memcpy() with a null source, even if count is zero (Leon Scroggins III). |
| Fixed bad link to RFC2083 in png.5 (Nikola Forro). |
