......@@ -5621,6 +5596,204 @@ Version 1.6.23rc02 [June 4, 2016]
Version 1.6.23 [June 9, 2016]
Fixed bad link to RFC2083 in png.5 (Nikola Forro).
Version 1.6.24beta01 [June 11, 2016]
Avoid potential overflow of the PNG_IMAGE_SIZE macro. This macro
is not used within libpng, but is used in some of the examples.
Version 1.6.24beta02 [June 23, 2016]
Correct filter heuristic overflow handling. This was broken when the
write filter code was moved out-of-line; if there is a single filter and
the heuristic sum overflows the calculation of the filtered line is not
completed. In versions prior to 1.6 the code was duplicated in-line
and the check not performed, so the filter operation completed; however,
in the multi-filter case where the sum is performed the 'none' filter would
be selected if all the sums overflowed, even if it wasn't in the filter
list. The fix to the first problem is simply to provide PNG_SIZE_MAX as
the current lmins sum value; this means the sum can never exceed it and
overflows silently. A reasonable compiler that does choose to inline
the code will simply eliminate the sum check.
The fix to the second problem is to use high precision arithmetic (this is
implemented in 1.7), however a simple safe fix here is to chose the lowest
numbered filter in the list from png_set_filter (this only works if the
first problem is also fixed) (John Bowler).
Use a more efficient absolute value calculation on SSE2 (Matthieu Darbois).
Fixed the case where PNG_IMAGE_BUFFER_SIZE can overflow in the application
as a result of the application using an increased 'row_stride'; previously
png_image_finish_read only checked for overflow on the base calculation of
components. (I.e. it checked for overflow of a 32-bit number on the total
number of pixel components in the output format, not the possibly padded row
length and not the number of bytes, which for linear formats is twice the
number of components.)
MSVC does not like '-(unsigned)', so replaced it with 0U-(unsigned)
MSVC does not like (uInt) = -(unsigned) (i.e. as an initializer), unless
the conversion is explicitly invoked by a cast.
Put the SKIP definition in the correct place. It needs to come after the
png.h include (see all the other .c files in contrib/libtests) because it
depends on PNG_LIBPNG_VER.
Removed the three compile warning options from the individual project
files into the zlib.props globals. It increases the warning level from 4
to All and adds a list of the warnings that need to be turned off. This is
semi-documentary; the intent is to tell libpng users which warnings have
been examined and judged non-fixable at present. The warning about
structure padding is fixable, but it would be a signficant change (moving
structure members around).
Version 1.6.24beta03 [July 4, 2016]
Optimized absolute value calculation in filter selection, similar to
code in the PAETH decoder in pngrutil.c. Build with PNG_USE_ABS to
use this.
Added pngcp to the build together with a pngcp.dfa configuration test.
Added high resolution timing to pngcp.
Added "Common linking failures" section to INSTALL.
Relocated misplaced #endif in png.c sRGB profile checking.
Fixed two Coverity issues in pngcp.c.
Version 1.6.24beta04 [July 8, 2016]
Avoid filter-selection heuristic sum calculations in cases where only one
filter is a candidate for selection. This trades off code size (added
private png_setup_*_row_only() functions) for speed.
Version 1.6.24beta05 [July 13, 2016]
Fixed some indentation to comply with our coding style.
Added contrib/tools/reindent.
Version 1.6.24beta06 [July 18, 2016]
Fixed more indentation to comply with our coding style.
Eliminated unnecessary tests of boolean png_isaligned() vs 0.
Version 1.6.24rc01 [July 25, 2016]
No changes.
Version 1.6.24rc02 [August 1, 2016]
Conditionally compile SSE2 headers in contrib/intel/intel_sse.patch
Conditionally compile png_decompress_chunk().
Version 1.6.24rc03 [August 2, 2016]
Conditionally compile ARM_NEON headers in pngpriv.h
Updated contrib/intel/intel_sse.patch
Version 1.6.24[August 4, 2016]
No changes.
Version 1.6.25beta01 [August 12, 2016]
Reject oversized iCCP profile immediately.
Cleaned up PNG_DEBUG compile of pngtest.c.
Conditionally compile png_inflate().
Version 1.6.25beta02 [August 18, 2016]
Don't install pngcp; it conflicts with pngcp in the pngtools package.
Minor editing of INSTALL, (whitespace, added copyright line)
Version 1.6.25rc01 [August 24, 2016]
No changes.
Version 1.6.25rc02 [August 29, 2016]
Added MIPS support (Mandar Sahastrabuddhe <Mandar.Sahastrabuddhe@imgtec.com>).
Only the UP filter is currently implemented.
Version 1.6.25rc03 [August 29, 2016]
Rebased contrib/intel/intel_sse.patch after the MIPS implementation.
Version 1.6.25rc04 [August 30, 2016]
Added MIPS support for SUB, AVG, and PAETH filters (Mandar Sahastrabuddhe).
Version 1.6.25rc05 [August 30, 2016]
Rebased contrib/intel/intel_sse.patch after the MIPS implementation update..
Version 1.6.25 [September 1, 2016]
No changes.
Version 1.6.26beta01 [September 26, 2016]
Fixed handling zero length IDAT in pngfix (bug report by Agostino Sarubbo,
bugfix by John Bowler).
Do not issue a png_error() on read in png_set_pCAL() because png_handle_pCAL
has allocated memory that libpng needs to free.
Conditionally compile png_set_benign_errors() in pngread.c and pngtest.c
Issue a png_benign_error instead of a png_error on ADLER32 mismatch
while decoding compressed data chunks.
Changed PNG_ZLIB_VERNUM to ZLIB_VERNUM in pngpriv.h, pngstruct.h, and
pngrutil.c.
If CRC handling of critical chunks has been set to PNG_CRC_QUIET_USE,
ignore the ADLER32 checksum in the IDAT chunk as well as the chunk CRCs.
Issue png_benign_error() on ADLER32 checksum mismatch instead of png_error().
Add tests/badcrc.png and tests/badadler.png to tests/pngtest.
Merged pngtest.c with libpng-1.7.0beta84/pngtest.c
Version 1.6.26beta02 [October 1, 2016]
Updated the documentation about CRC and ADLER32 handling.
Quieted 117 warnings from clang-3.8 in pngtrans.c, pngread.c,
pngwrite.c, pngunknown.c, and pngvalid.c.
Quieted 58 (out of 144) -Wconversion compiler warnings by changing
flag definitions in pngpriv.h from 0xnnnn to 0xnnnnU and trivial changes
in png.c, pngread.c, and pngwutil.c.
Version 1.6.26beta03 [October 2, 2016]
Removed contrib/libtests/*.orig and *.rej that slipped into the tarballs.
Quieted the 86 remaining -Wconversion compiler warnings by
revising the png_isaligned() macro and trivial changes in png.c,
pngerror.c, pngget.c, pngmem.c, pngset.c, pngrtran.c, pngrutil.c,
pngwtran.c, pngwrite.c, and pngwutil.c.
Version 1.6.26beta04 [October 3, 2016]
Quieted (bogus?) clang warnings about "absolute value has no effect"
when PNG_USE_ABS is defined.
Fixed offsets in contrib/intel/intel_sse.patch
Version 1.6.26beta05 [October 6, 2016]
Changed integer constant 4294967294 to unsigned 4294967294U in pngconf.h
to avoid a signed/unsigned compare in the preprocessor.
Version 1.6.26beta06 [October 7, 2016]
Use zlib-1.2.8.1 inflateValidate() instead of inflateReset2() to
optionally avoid ADLER32 evaluation.
Version 1.6.26rc01 [October 12, 2016]
No changes.
Version 1.6.26 [October 20, 2016]
Cosmetic change, "ptr != 0" to "ptr != NULL" in png.c and pngrutil.c
Despammed email addresses (replaced "@" with " at ").
Version 1.6.27beta01 [November 2, 2016]
Restrict the new ADLER32-skipping to IDAT chunks. It broke iCCP chunk
handling: an erroneous iCCP chunk would throw a png_error and reject the
entire PNG image instead of rejecting just the iCCP chunk with a warning,
if built with zlib-1.2.8.1.
Version 1.6.27rc01 [December 27, 2016]
Control ADLER32 checking with new PNG_IGNORE_ADLER32 option.
Removed the use of a macro containing the pre-processor 'defined'
operator. It is unclear whether this is valid; a macro that
"generates" 'defined' is not permitted, but the use of the word
"generates" within the C90 standard seems to imply more than simple
substitution of an expression itself containing a well-formed defined
operation.
Added ARM support to CMakeLists.txt (Andreas Franek).
Version 1.6.27 [December 29, 2016]
Fixed a potential null pointer dereference in png_set_text_2() (bug report
and patch by Patrick Keshishian, CVE-2016-10087).
Version 1.6.28rc01 [January 3, 2017]
Fixed arm/aarch64 detection in CMakeLists.txt (Gianfranco Costamagna).
Added option to Cmake build allowing a custom location of zlib to be
specified in a scenario where libpng is being built as a subproject
alongside zlib by another project (Sam Serrels).
Changed png_ptr->options from a png_byte to png_uint_32, to accomodate
up to 16 options.
Version 1.6.28rc02 [January 4, 2017]
Added "include(GNUInstallDirs)" to CMakeLists.txt (Gianfranco Costamagna).
Moved SSE2 optimization code into the main libpng source directory.
Configure libpng with "configure --enable-intel-sse" or compile
libpng with "-DPNG_INTEL_SSE" in CPPFLAGS to enable it.
Version 1.6.28rc03 [January 4, 2017]
Backed out the SSE optimization and last CMakeLists.txt to allow time for QA.
Version 1.6.28 [January 5, 2017]
No changes.
