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).
