eb0bf4f468 [libpng16] Updated pngvalid.c with recent changes from libpng17 2015-09-18 13:09:57 -05:00

1e16e8829d [libpng16] Fix typo (extra "*/") in contrib/libtests/fakepng.c 2015-09-15 17:07:34 -05:00

33a97c5c8a [libpng16] Fixed png_save_int_32 when int is not 2's complement (John Bowler). 2015-08-21 14:42:00 -05:00

39be3b81da [libpng16] Bump version to 1.6.19beta03 2015-08-19 12:58:26 -05:00
John Bowler
2d62f7406f [libpng16] 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).

167b5e4c27 [libpng16] Safely convert num_bytes to a png_byte in png_set_sig_bytes() 2015-08-17 21:20:34 -05:00

a8242fe6fb [libng16] Reverted recent mistaken change of 0xnnnn to 0xnnnnUL 2015-08-17 20:46:27 -05:00
John Bowler
751cee5ef1 [libpng16] 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).

8ba4b13c55 [libpng16] Changed 0xnnnn constants to 0xnnnnUL. 2015-08-16 22:49:58 -05:00

8b83ff3704 [libpng16] Change "n bit" to "n-bit" in comments. 2015-08-13 20:57:18 -05:00

4e1d299e6b [libpng16] Removed unreachable "break" statements in png.c, pngread.c, and 
pngrtran.c to suppress clang warnings (Bug report by Viktor Szakats).

0e9cd91609 [libpng16] 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).

8510247b5f [libpng16] Fixed uninitialized variable in contrib/gregbook/rpng2-x.c and 
fixed potential leak of png_pixels in contrib/pngminus/pnm2png.c

e485a09e0e [libpng16] Suppressed some warnings from the Borland C++ 5.5.1/5.82 compiler 
(Bug report by Viktor Szaka'ts).  Several warnings remain and are
unavoidable, where we test for overflow.

1fa62ae734 [libpng16] Rearranged png.h to put the major sections in the same order as 
in libpng17.

Glenn Randers-Pehrson
b9e5e5f5a8 [libpng16] Replaced arbitrary use of 'extern' with #define PNG_LINKAGE_*. To 
preserve API compatibility, the new defines all default to "extern"
(requested by Jan Nijtmans).

81487c8b54 [libpng16] Removed some unused WEIGHTED_FILTER macros from png.h and pngstruct.h 2015-06-10 07:06:42 -05:00

f6e7551f06 [libpng16] Eliminated the final two Coverity defects (insecure temporary file 
handling in contrib/libtests/pngstest.c; possible overflow of
unsigned char in contrib/tools/png-fix-itxt.c). To use the "secure"
file handling, define PNG_USE_MKSTEMP, otherwise "tmpfile()" will
continue to be used.

Glenn Randers-Pehrson
b26b51d154 [libpng16] Quieted Coverity issues in pngfix.c, png-fix-itxt.c, pngvalid.c, 
pngstest.c, and pngimage.c. Most seem harmless, but png-fix-itxt
would only work with iTXt chunks with length 255 or less.

John Bowler
b780eba4e4 [libpng16] Fixed cexcept.h in which GCC 5 now reports that one of the auto 
variables in the Try macro needs to be volatile to prevent value
being lost over the setjmp.

25bfb13770 [libpng16] Removed non-working progressive reader 'skip' function. This 
function has apparently never been used. It was implemented
to support back-door modification of png_struct in libpng-1.4.x
but was apparently never tested (because it does nothing and cannot
do anything).

Glenn Randers-Pehrson
89edbf8317 [libpng16] Removed WRITE_WEIGHTED_FILTERED code, to save a few kbytes of the 
compiled library size. It never worked properly and as far as we can
tell, no one uses it. The png_set_filter_heuristics() and
png_set_filter_heuristics_fixed() APIs are retained but deprecated
and do nothing.

1088f4925f [libpng16] Fixed old cut&paste bug in the weighted filter selection code in 
pngwutil.c, introduced in libpng-0.95, March 1997.

b66de48b3b [libpng16] Changed png_voidcast(), etc., to voidcast(), etc., in 
contrib/tools/pngfix.c to avoid confusion with the libpng private macros.
 2015-05-30 22:57:33 -05:00
Glenn Randers-Pehrson
e6877671f1 [libpng16] Backported filter selection code from libpng-1.7.0beta51, to combine 
sub_row, up_row, avg_row, and paeth_row into try_row and tst_row.

d2fedd629d [libpng16] Avoid Coverity issue 80858 (REVERSE NULL) in pngtest.c 
PNG_DEBUG builds.

8ee821e69a [libpng16] PNG_RELEASE_BUILD replaces tests where the code depended on the build base 
type and can be defined on the command line, allowing testing in beta builds. Back
ported from libpng17.
