png_decompress_chunk(), and remove "chunkdata" from parameter list.

Revised png_check_chunk_name() to reject a name with a lowercase 3rd byte.

Version 1.6.16rc01 [December 21, 2014]

Restored a test on width that was removed from png.c at libpng-1.6.9
|

(Bug report by Alex Eubanks).

(Bug report by Alex Eubanks, CVE-2015-0973).

Version 1.6.16rc02 [December 21, 2014]
|
||||
Undid the update to pngrutil.c in 1.6.16rc01.
|

|

Version 1.6.16rc03 [December 21, 2014]

Fixed an overflow in png_combine_row with very wide interlaced images.
|

Fixed an overflow in png_combine_row() with very wide interlaced images
|

(Bug report and fix by John Bowler, CVE-2014-9495).
|

|

Version 1.6.16 [December 22, 2014]
|

No changes.
|
||||
|
||||
Version 1.6.17beta01 [January 29, 2015]
|
||||
Removed duplicate PNG_SAFE_LIMITS_SUPPORTED handling from pngconf.h
|
||||
Corrected the width limit calculation in png_check_IHDR().
|
||||
Removed user limits from pngfix. Also pass NULL pointers to
|
||||
png_read_row to skip the unnecessary row de-interlace stuff.
|
||||
Added testing of png_set_packing() to pngvalid.c
|
||||
Regenerated configure scripts in the *.tar distributions with libtool-2.4.4
|
||||
Implement previously untested cases of libpng transforms in pngvalid.c
|
||||
Fixed byte order in 2-byte filler, in png_do_read_filler().
|
||||
Made the check for out-of-range values in png_set_tRNS() detect
|
||||
values that are exactly 2^bit_depth, and work on 16-bit platforms.
|
||||
Merged some parts of libpng-1.6.17beta01 and libpng-1.7.0beta47.
|
||||
Added #ifndef __COVERITY__ where needed in png.c, pngrutil.c and
|
||||
pngset.c to avoid warnings about dead code.
|
||||
Added "& 0xff" to many instances of expressions that are typecast
|
||||
to (png_byte), to avoid Coverity gripes.
|
||||
|
||||
Version 1.6.17beta02 [February 7, 2015]
|
||||
Work around one more Coverity-scan dead-code warning.
|
||||
Do not build png_product2() when it is unused.
|
||||
|
||||
Version 1.6.17beta03 [February 17, 2015]
|
||||
Display user limits in the output from pngtest.
|
||||
Eliminated the PNG_SAFE_LIMITS macro and restored the 1-million-column
|
||||
and 1-million-row default limits in pnglibconf.dfa, that can be reset
|
||||
by the user at build time or run time. This provides a more robust
|
||||
defense against DOS and as-yet undiscovered overflows.
|
||||
|
||||
Version 1.6.17beta04 [February 21, 2015]
|
||||
Added PNG_WRITE_CUSTOMIZE_COMPRESSION_SUPPORTED macro, on by default.
|
||||
Allow user to call png_get_IHDR() with NULL arguments (Reuben Hawkins).
|
||||
Rebuilt configure scripts with automake-1.15 and libtool-2.4.6
|
||||
|
||||
Version 1.6.17beta05 [February 25, 2015]
|
||||
Restored compiling of png_reciprocal2 with PNG_NO_16BIT.
|
||||
|
||||
Version 1.6.17beta06 [February 27, 2015]
|
||||
Moved png_set_filter() prototype into a PNG_WRITE_SUPPORTED block
|
||||
of png.h.
|
||||
Avoid runtime checks when converting integer to png_byte with
|
||||
Visual Studio (Sergey Kosarevsky)
|
||||
|
||||
Version 1.6.17rc01 [March 4, 2015]
|
||||
No changes.
|
||||
|
||||
Version 1.6.17rc02 [March 9, 2015]
|
||||
Removed some comments that the configure script did not handle
|
||||
properly from scripts/pnglibconf.dfa and pnglibconf.h.prebuilt.
|
||||
Free the unknown_chunks structure even when it contains no data.
|
||||
|
||||
Version 1.6.17rc03 [March 12, 2015]
|
||||
Updated CMakeLists.txt to add OSX framework, change YES/NO to ON/OFF
|
||||
for consistency, and remove some useless tests (Alexey Petruchik).
|
||||
|
||||
Version 1.6.17rc04 [March 16, 2015]
|
||||
Remove pnglibconf.h, pnglibconf.c, and pnglibconf.out instead of
|
||||
pnglibconf.* in "make clean" (Cosmin).
|
||||
Fix bug in calculation of maxbits, in png_write_sBIT, introduced
|
||||
in libpng-1.6.17beta01 (John Bowler).
|
||||
|
||||
Version 1.6.17rc05 [March 21, 2015]
|
||||
Define PNG_FILTER_* and PNG_FILTER_VALUE_* in png.h even when WRITE
|
||||
is not supported (John Bowler). This fixes an error introduced in
|
||||
libpng-1.6.17beta06.
|
||||
Reverted "& 0xff" additions of version 1.6.17beta01. Libpng passes
|
||||
the Coverity scan without them.
|
||||
|
||||
Version 1.6.17rc06 [March 23, 2015]
|
||||
Remove pnglibconf.dfn and pnglibconf.pre with "make clean".
|
||||
Reformatted some "&0xff" instances to "& 0xff".
|
||||
Fixed simplified 8-bit-linear to sRGB alpha. The calculated alpha
|
||||
value was wrong. It's not clear if this affected the final stored
|
||||
value; in the obvious code path the upper and lower 8-bits of the
|
||||
alpha value were identical and the alpha was truncated to 8-bits
|
||||
rather than dividing by 257 (John Bowler).
|
||||
|
||||
Version 1.6.17 [March 26, 2015]
|
||||
No changes.
