Update png to 1.6.19:
Libpng 1.6.19 - November 12, 2015
Changes since the last public release (1.6.18):
Updated obsolete information about the simplified API macros in the
manual pages (Bug report by Arc Riley).
Avoid potentially dereferencing NULL info_ptr in png_info_init_3().
Rearranged png.h to put the major sections in the same order as
in libpng17.
Eliminated unused PNG_COST_SHIFT, PNG_WEIGHT_SHIFT, PNG_COST_FACTOR, and
PNG_WEIGHT_FACTOR macros.
Suppressed some warnings from the Borland C++ 5.5.1/5.82 compiler
(Bug report by Viktor Szakats). Several warnings remain and are
unavoidable, where we test for overflow.
Fixed potential leak of png_pixels in contrib/pngminus/pnm2png.c
Fixed uninitialized variable in contrib/gregbook/rpng2-x.c
Moved config.h.in~ from the "libpng_autotools_files" list to the
"libpng_autotools_extra" list in autogen.sh because it was causing a
false positive for missing files (bug report by Robert C. Seacord).
Removed unreachable "break" statements in png.c, pngread.c, and pngrtran.c
to suppress clang warnings (Bug report by Viktor Szakats).
Fixed some bad links in the man page.
Changed "n bit" to "n-bit" in comments.
Added signed/unsigned 16-bit safety net. This removes the dubious
0x8000 flag definitions on 16-bit systems. They aren't supported
yet the defs *probably* work, however it seems much safer to do this
and be advised if anyone, contrary to advice, is building libpng 1.6
on a 16-bit system. It also adds back various switch default clauses
for GCC; GCC errors out if they are not present (with an appropriately
high level of warnings).
Safely convert num_bytes to a png_byte in png_set_sig_bytes() (Robert
Seacord).
Fixed the recently reported 1's complement security issue by replacing
the value that is illegal in the PNG spec, in both signed and unsigned
values, with 0. Illegal unsigned values (anything greater than or equal
to 0x80000000) can still pass through, but since these are not illegal
in ANSI-C (unlike 0x80000000 in the signed case) the checking that
occurs later can catch them (John Bowler).
Fixed png_save_int_32 when int is not 2's complement (John Bowler).
Updated libpng16 with all the recent test changes from libpng17,
including changes to pngvalid.c to ensure that the original,
distributed, version of contrib/visupng/cexcept.h can be used
(John Bowler).
pngvalid contains the correction to the use of SAVE/STORE_
UNKNOWN_CHUNKS; a bug revealed by changes in libpng 1.7. More
tests contain the --strict option to detect warnings and the
pngvalid-standard test has been corrected so that it does not
turn on progressive-read. There is a separate test which does
that. (John Bowler)
Also made some signed/unsigned fixes.
Make pngstest error limits version specific. Splitting the machine
generated error structs out to a file allows the values to be updated
without changing pngstest.c itself. Since libpng 1.6 and 1.7 have
slightly different error limits this simplifies maintenance. The
makepngs.sh script has also been updated to more accurately reflect
current problems in libpng 1.7 (John Bowler).
Incorporated new test PNG files into make check. tests/pngstest-*
are changed so that the new test files are divided into 8 groups by
gamma and alpha channel. These tests have considerably better code
and pixel-value coverage than contrib/pngsuite; however,coverage is
still incomplete (John Bowler).
Removed the '--strict' in 1.6 because of the double-gamma-correction
warning, updated pngstest-errors.h for the errors detected with the
new contrib/testspngs PNG test files (John Bowler).
Worked around rgb-to-gray issues in libpng 1.6. The previous
attempts to ignore the errors in the code aren't quite enough to
deal with the 'channel selection' encoding added to libpng 1.7; abort.
Fixed 'pow' macros in pngvalid.c. It is legal for 'pow' to be a
macro, therefore the argument list cannot contain preprocessing
directives. Make sure pow is a function where this happens. This is
a minimal safe fix, the issue only arises in non-performance-critical
code (bug report by Curtis Leach, fix by John Bowler).
Added sPLT support to pngtest.c
Prevent setting or writing over-length PLTE chunk (Cosmin Truta).
Silently truncate over-length PLTE chunk while reading.
Libpng incorrectly calculated the output rowbytes when the application
decreased either the number of channels or the bit depth (or both) in
a user transform. This was safe; libpng overallocated buffer space
(potentially by quite a lot; up to 4 times the amount required) but,
from 1.5.4 on, resulted in a png_error (John Bowler).
Fixed some inconsequential cut-and-paste typos in
png_set_cHRM_XYZ_fixed().
Clarified COPYRIGHT information to state explicitly that versions
are derived from previous versions.
Removed much of the long list of previous versions from png.h and
libpng.3.
