2dca15686f [libpng16] Moved chunk-length check into a png_check_chunk_length() private 
function (Suggested by Max Stepin).

2dbef2f2a9 [libpng16] Restored IDAT length check. Previously the calculated limit was five 
bytes too small (neglected to account for a partial DEFLATE buffer)

4ac8b5e0d6 [libpng16] Use png_debug2() instead of printf() for bug reporting. 2017-08-03 16:29:58 -05:00

095b4ce16b [libpng16] Disabled new limit test on IDAT chunks. It was producing too small 
a limit for some files.

d930d36155 [libpng16] Restored png_get_eXIf_1() and png_set_eXIf_1() because strlen(eXIf_buf) 
does not work (the eXIf chunk data can contain zeroes).
 2017-08-03 10:29:10 -05:00

a1fe2c9848 [libpng16] Check length of IDAT against maximum possible IDAT size, accounting 
for height, rowbytes, interlacing and zlib/deflate overhead.

3524b0d201 [libpng16] Update "Last changed" dates and some copyright years 2017-07-31 17:03:17 -05:00
Glenn Randers-Pehrson
3e753f5cbe [libpng16] Changed name of png_get_eXIF and png_set_eXIf() to png_get_eXIf_1() 
and png_set_eXIf_1(), respectively, to avoid breaking API compatibility
with libpng-1.6.31.
 2017-07-31 16:56:30 -05:00
Glenn Randers-Pehrson
40afb68570 [libpng16] Added calls to png_handle_eXIf(() in pngread.c and png_write_eXIf() 
in pngwrite.c, and made various other fixes to png_write_eXIf().
Eliminated png_ptr->num_exif member from pngstruct.h and added num_exif
  to arguments for png_get_eXIf() and png_set_eXIf().

4ab78af90a [libpng16] Avoid possible NULL dereference in png_handle_eXIf when benign_errors 
are allowed. Avoid leaking the input buffer "eXIf_buf".

68cb0aaee3 [libpng16] Implement eXIf chunk support 2017-07-13 11:22:48 -05:00
John Bowler
72d07d3202 [libpng16] Removed one of the GCC-7.1.0 'strict-overflow' warnings that 
result when integers appear on both sides of a compare.  Worked around the
  others by forcing the strict-overflow setting in the relevant functions to
  a level where they are not reported.
Changed "FALL THROUGH" comments to "FALLTHROUGH" because GCC doesn't like
  the space.
Worked around some C-style casts from (void*) because g++ 5.4.0 objects
  to them.
Increased the buffer size for 'sprint' to pass the gcc 7.1.0 'sprint
  overflow' check that is on by default with -Wall -Wextra.

a7029a5b4c [libpng16] Change test ZLIB_VERNUM >= 0x1281 to ZLIB_VERNUM >= 0x1290 in 
pngrutil.c because Solaris 11 distributes zlib-1.2.8.f that is older
than 1.2.8.1.
