Update to 1.5.5 to fix CVE-2011-3328, requested by tron.
Version 1.5.5beta01 [July 13, 2011]
Fixed some typos and made other minor changes in the manual.
Updated contrib/pngminus/makefile.std (Samuli Souminen)
Version 1.5.5beta02 [July 14, 2011]
Revised Makefile.am and Makefile.in to look in the right directory for
pnglibconf.h.prebuilt
Version 1.5.5beta03 [July 27, 2011]
Enabled compilation with g++ compiler. This compiler does not recognize
the file extension, so it always compiles with C++ rules. Made minor
changes to pngrutil.c to cast results where C++ expects it but C does not.
Minor editing of libpng.3 and libpng-manual.txt.
Version 1.5.5beta04 [July 29, 2011]
Revised CMakeLists.txt (Clifford Yapp)
Updated commentary about the png_rgb_to_gray() default coefficients
in the manual and in pngrtran.c
Version 1.5.5beta05 [August 17, 2011]
Prevent unexpected API exports from non-libpng DLLs on Windows. The "_DLL"
is removed from the test of whether a DLL is being built (this erroneously
caused the libpng APIs to be marked as DLL exports in static builds under
Microsoft Visual Studio). Almost all of the libpng building configuration
is moved from pngconf.h to pngpriv.h, but PNG_DLL_EXPORT remains in
pngconf.h, though, so that it is colocated with the import definition (it
is no longer used anywhere in the installed headers). The VStudio project
definitions have been cleaned up: "_USRDLL" has been removed from the
static library builds (this was incorrect), and PNG_USE_DLL has been added
to pngvalid to test the functionality (pngtest does not supply it,
deliberately). The spurious "_EXPORTS" has been removed from the
libpng build (all these errors were a result of copy/paste between project
configurations.)
Added new types and internal functions for CIE RGB end point handling to
pngpriv.h (functions yet to be implemented).
Version 1.5.5beta06 [August 26, 2011]
Ensure the CMAKE_LIBRARY_OUTPUT_DIRECTORY is set in CMakeLists.txt
(Clifford Yap)
Fixes to rgb_to_gray and cHRM XYZ APIs (John Bowler):
The rgb_to_gray code had errors when combined with gamma correction.
Some pixels were treated as true grey when they weren't and such pixels
and true grey ones were not gamma corrected (the original value of the
red component was used instead). APIs to get and set cHRM using color
space end points have been added and the rgb_to_gray code that defaults
based on cHRM, and the divide-by-zero bug in png_handle_cHRM (CERT
VU#477046, CVE-2011-3328, introduced in 1.5.4) have been corrected.
A considerable number of tests has been added to pngvalid for the
rgb_to_gray transform.
Arithmetic errors in rgb_to_gray whereby the calculated gray value was
truncated to the bit depth rather than rounded have been fixed except in
the 8-bit non-gamma-corrected case (where consistency seems more important
than correctness.) The code still has considerable inaccuracies in the
8-bit case because 8-bit linear arithmetic is used.
Version 1.5.5beta07 [September 7, 2011]
Added "$(ARCH)" option to makefile.darwin
Added SunOS support to configure.ac and Makefile.am
Changed png_chunk_benign_error() to png_warning() in png.c, in
png_XYZ_from_xy_checked().
Version 1.5.5beta08 [September 10, 2011]
Fixed 64-bit compilation errors (gcc). The errors fixed relate
to conditions where types that are 32 bits in the GCC 32-bit
world (uLong and png_size_t) become 64 bits in the 64-bit
world. This produces potential truncation errors that the
compiler correctly flags.
Relocated new HAVE_SOLARIS_LD definition in configure.ac
Constant changes for 64-bit compatibility (removal of L suffixes). The
16-bit cases still use "L" as we don't have a 16-bit test system.
Version 1.5.5rc01 [September 17, 2011]
Removed "L" suffixes from constants in pngpriv.h
Version 1.5.5 [September 22, 2011]
No changes.

COMMENT= Library for manipulating PNG images

Update to 1.5.1beta01:
1.5.1beta01 contains a security fix for 1.5.0.
The current public release, libpng 1.5.0, continues the evolution
of the libpng API, finally hiding the contents of the venerable
and hoary png_struct and png_info data structures inside private
(i.e., non-installed) header files. (Apps that compiled with libpng
1.4 without warnings about deprecated features should happily
compile with 1.5, too.) It also includes a new, more thorough test
program (pngvalid.c), a new pnglibconf.h header file that tracks
what features were enabled or disabled when libpng was built, and
huge thanks to John Bowler, who did most of the work. Complete
differences relative to libpng 1.4.x are detailed at
http://www.libpng.org/pub/png/src/libpng-1.4.x-to-1.5.x-summary.txt .
Since the shlib name changed, next up: PKGREVISION++ all across pkgsrc.

Update to 1.4.2. Shared library name changes from libpn12.* to libpng14.*,
so bump ABI depends.
Remove libpng.* from package, instead use buildlink to help some packages
that are looking for the library themselves instead of using pkg-config
or libpng-config.
Changes:
version 1.4.2:
Restored the macro definition of png_check_sig().
Conditionally compile an "else" statement in png_decompress_chunk().
Documented the fact that png_set_dither() was disabled since libpng-1.4.0.
Reenabled png_set_dither() but renamed it to png_set_quantize() to reflect
more accurately what it actually does. At the same time, renamed
the PNG_DITHER_[RED,GREEN_BLUE]_BITS macros to
PNG_QUANTIZE_[RED,GREEN,BLUE]_BITS.
Added some "(long)" typecasts to printf calls in png_handle_cHRM().
Relaxed the overly-restrictive permissions of some files.
Added the "vstudio" project to replace "visualc6" and "visualc71" which
will be removed from libpng-1.5.0.
Demonstrate in example.c that lang_key should be initialized.
Set PNG_NO_READ_BGR, PNG_NO_IO_STATE, and PNG_NO_TIME_RFC1123 in
contrib/pngminim/decoder/pngusr.h to make a smaller decoder application.
Include png_reset_zstream() in png.c only when PNG_READ_SUPPORTED is defined.
Removed dummy_inflate.c and uncompr.c from contrib/pngminim/encoder
Corrected PNG_UNKNOWN_CHUNKS_SUPPORTED to PNG_HANDLE_AS_UNKNOWN_SUPPORTED
in gregbook/readpng2.c
Corrected protection of png_get_user_transform_ptr. The API declaration in
png.h is removed if both READ and WRITE USER_TRANSFORM are turned off
but was left defined in pngtrans.c
Moved declarations of umsg[] inside the proper #ifdef blocks in pngrutil.c
version 1.4.1 [February 25, 2010]
Updated CMakeLists.txt for consistent indentation and to avoid an
unclosed if-statement warning (Philip Lowman).
Revised Makefile.am and Makefile.in to remove references to Y2KINFO,
KNOWNBUG, and libpng.la (Robert Schwebel).
Revised the makefiles to install the same files and symbolic
except for libpng.la and libpng14.la.
Make png_set|get_compression_buffer_size() available even when
PNG_WRITE_SUPPORTED is not enabled.
Revised Makefile.am and Makefile.in to simplify their maintenance.
Revised the makefiles to install a link to libpng14.so.14.1
Removed png_set_premultiply_alpha() from scripts/*.def
Revised png_decompress_chunk() to improve speed and memory usage when
decoding large chunks, using a two-pass method suggested by John Bowler.
Added png_set|get_chunk_malloc_max() functions.
Relocated "int k" declaration in pngtest.c to minimize its scope.
Folded some long lines in the source files.
Added defineable PNG_USER_CHUNK_CACHE_MAX and PNG_USER_CHUNK_MALLOC_MAX
Eliminated use of png_ptr->irowbytes and reused the slot in png_ptr as
png_ptr->png_user_chunk_malloc_max.
Return allocated "old_buffer" in png_push_save_buffer() before calling
png_error(), to avoid a potential memory leak.
Removed the cbuilder5 project, which has not been updated to 1.4.0.
Complete rewrite of two-pass png_decompress_chunk() by John Bowler.
Removed obsolete unused MMX-querying support from contrib/gregbook
Removed the AIX redefinition of jmpbuf in png.h
Define _ALL_SOURCE in configure.ac, makefile.aix, and CMakeLists.txt
when using AIX compiler.
Removed unused gzio.c from contrib/pngminim gather and makefile scripts
Changes to Libpng from version 1.2.42 to 1.4.0 (January 4, 2010)
Libpng-1.4.0 was released by the PNG Development Group on January
3, 2010. Important new features include support for the iTXt chunk
and a function for limiting the amount of memory that a possibly
malicious compressed chunk can consume. Some long-deprecated functions
and features have been removed. A new private header file that is
not visible to applications has been created, to improve our ability
to maintain binary compatibility among future libpng versions.
Specifically,
1. Private libpng prototypes and macro definitions were moved from
png.h and pngconf.h into a new pngpriv.h header file that is not
visible to applications.
2. Some obsolete/deprecated macros and functions have been removed.
a. We eliminated the obsolete, unused pnggccrd.c and pngvcrd.c files
and related makefiles.
b. We removed the typecasted NULL definitions such as
#define png_voidp_NULL (png_voidp)NULL
If you used these in your application, just use NULL instead.
c. We eliminated the PNG_1_0_X and PNG_1_2_X macros.
d. We eliminated the PNG_LEGACY_SUPPORTED macro.
e. We removed many WIN32_WCE #ifdefs.
f. We removed the functions png_read_init(info_ptr),
png_write_init(info_ptr), png_info_init(info_ptr),
png_read_destroy(), and png_write_destroy().
They have been deprecated since libpng-0.95.
g. We removed the png_permit_empty_plte() function. It has been
deprecated since libpng-1.0.9. Use png_permit_mng_features() instead.
h. We removed the obsolete stub functions png_get_mmx_flagmask(),
png_set_mmx_thresholds(), png_get_asm_flags(),
png_get_mmx_bitdepth_threshold(), png_get_mmx_rowbytes_threshold(),
png_set_asm_flags(), and png_mmx_supported()
i. We removed the obsolete png_check_sig(), png_memcpy_check(), and
png_memset_check() functions. Instead use !png_sig_cmp(),
png_memcpy(), and png_memset(), respectively, i.e.,
replace
png_check_sig(buf, 8)
with
png_sig_cmp(buf, 0, 8) == 0
replace
png_memcpy_check(png_ptr, dest, src, length)
with
png_memcpy(dest, src, length)
and replace
png_memset_check(png_ptr, dest, value, length)
with
png_memset(dest, value, length)
j. We removed support for global arrays to improve thread safety.
k. We removed support for numbered error messages by default, since we
never got around to actually numbering the error messages. The function
png_set_strip_error_numbers() was removed from the library by default.
l. The png_zalloc() and png_zfree() functions are no longer exported.
The png_zalloc() function no longer zeroes out the memory that it
allocates.
m. The function png_set_gray_1_2_4_to_8() was removed. It has been
deprecated since libpng-1.0.18 and 1.2.9, when it was replaced with
png_set_expand_gray_1_2_4_to_8() because the former function also
expanded palette images.
3. Several function prototypes were changed.
a. We changed the prototype for png_malloc() from
png_malloc(png_structp png_ptr, png_uint_32 size) to
png_malloc(png_structp png_ptr, png_alloc_size_t size)
b. We changed the prototypes of png_get_compression_buffer_size() and
png_set_compression_buffer_size() to work with png_size_t instead of
png_uint_32.
4. We added some new features:
a. We enabled iTXt chunk support by default. This changes the png_text
structure by adding the itxt_length, lang, and lang_key members.
b. We added the functions png_set_benign_errors(), png_benign_error(),
and png_chunk_benign_error(). With these, you can choose to treat
certain normally fatal errors as nonfatal.
c. Support for setting the maximum amount of memory that the application
will allocate for reading chunks was added, as a security measure.
The functions png_set_chunk_cache_max() and png_get_chunk_cache_max()
were added to the library.
d. We added the png_calloc() function and used it in place of
of "png_malloc(); png_memset();" except in the case in png_read_png()
where the array consists of pointers; in this case a "for" loop is used
after the png_malloc() to set the pointers to NULL, to give robust.
behavior in case the application runs out of memory part-way through
the process.
e. We implemented support for I/O states by adding png_ptr member io_state
and functions png_get_io_chunk_name() and png_get_io_state() in pngget.c
f. We added PNG_TRANSFORM_GRAY_TO_RGB to the available high-level
input transforms.
5. Other changes
a. We changed the names of the png_struct and info_struct members "trans"
and "trans_values" to "trans_alpha" and "trans_color", respectively.
b. Checking for and reporting of errors in the IHDR chunk is more thorough.
c. We removed the trailing '.' from the warning and error messages.
d. Direct access to png_ptr->jmpbuf has been deprecated since libpng
version 1.0.6, and libpng now generates a warning about it.
To avoid such warnings, change
setjmp(png_ptr->jmpbuf)
to
setjmp(png_jmpbuf(png_ptr))

Update to 1.4.2. Shared library name changes from libpn12.* to libpng14.*,
so bump ABI depends.
Remove libpng.* from package, instead use buildlink to help some packages
that are looking for the library themselves instead of using pkg-config
or libpng-config.
Changes:
version 1.4.2:
Restored the macro definition of png_check_sig().
Conditionally compile an "else" statement in png_decompress_chunk().
Documented the fact that png_set_dither() was disabled since libpng-1.4.0.
Reenabled png_set_dither() but renamed it to png_set_quantize() to reflect
more accurately what it actually does. At the same time, renamed
the PNG_DITHER_[RED,GREEN_BLUE]_BITS macros to
PNG_QUANTIZE_[RED,GREEN,BLUE]_BITS.
Added some "(long)" typecasts to printf calls in png_handle_cHRM().
Relaxed the overly-restrictive permissions of some files.
Added the "vstudio" project to replace "visualc6" and "visualc71" which
will be removed from libpng-1.5.0.
Demonstrate in example.c that lang_key should be initialized.
Set PNG_NO_READ_BGR, PNG_NO_IO_STATE, and PNG_NO_TIME_RFC1123 in
contrib/pngminim/decoder/pngusr.h to make a smaller decoder application.
Include png_reset_zstream() in png.c only when PNG_READ_SUPPORTED is defined.
Removed dummy_inflate.c and uncompr.c from contrib/pngminim/encoder
Corrected PNG_UNKNOWN_CHUNKS_SUPPORTED to PNG_HANDLE_AS_UNKNOWN_SUPPORTED
in gregbook/readpng2.c
Corrected protection of png_get_user_transform_ptr. The API declaration in
png.h is removed if both READ and WRITE USER_TRANSFORM are turned off
but was left defined in pngtrans.c
Moved declarations of umsg[] inside the proper #ifdef blocks in pngrutil.c
version 1.4.1 [February 25, 2010]
Updated CMakeLists.txt for consistent indentation and to avoid an
unclosed if-statement warning (Philip Lowman).
Revised Makefile.am and Makefile.in to remove references to Y2KINFO,
KNOWNBUG, and libpng.la (Robert Schwebel).
Revised the makefiles to install the same files and symbolic
except for libpng.la and libpng14.la.
Make png_set|get_compression_buffer_size() available even when
PNG_WRITE_SUPPORTED is not enabled.
Revised Makefile.am and Makefile.in to simplify their maintenance.
Revised the makefiles to install a link to libpng14.so.14.1
Removed png_set_premultiply_alpha() from scripts/*.def
Revised png_decompress_chunk() to improve speed and memory usage when
decoding large chunks, using a two-pass method suggested by John Bowler.
Added png_set|get_chunk_malloc_max() functions.
Relocated "int k" declaration in pngtest.c to minimize its scope.
Folded some long lines in the source files.
Added defineable PNG_USER_CHUNK_CACHE_MAX and PNG_USER_CHUNK_MALLOC_MAX
Eliminated use of png_ptr->irowbytes and reused the slot in png_ptr as
png_ptr->png_user_chunk_malloc_max.
Return allocated "old_buffer" in png_push_save_buffer() before calling
png_error(), to avoid a potential memory leak.
Removed the cbuilder5 project, which has not been updated to 1.4.0.
Complete rewrite of two-pass png_decompress_chunk() by John Bowler.
Removed obsolete unused MMX-querying support from contrib/gregbook
Removed the AIX redefinition of jmpbuf in png.h
Define _ALL_SOURCE in configure.ac, makefile.aix, and CMakeLists.txt
when using AIX compiler.
Removed unused gzio.c from contrib/pngminim gather and makefile scripts
Changes to Libpng from version 1.2.42 to 1.4.0 (January 4, 2010)
Libpng-1.4.0 was released by the PNG Development Group on January
3, 2010. Important new features include support for the iTXt chunk
and a function for limiting the amount of memory that a possibly
malicious compressed chunk can consume. Some long-deprecated functions
and features have been removed. A new private header file that is
not visible to applications has been created, to improve our ability
to maintain binary compatibility among future libpng versions.
Specifically,
1. Private libpng prototypes and macro definitions were moved from
png.h and pngconf.h into a new pngpriv.h header file that is not
visible to applications.
2. Some obsolete/deprecated macros and functions have been removed.
a. We eliminated the obsolete, unused pnggccrd.c and pngvcrd.c files
and related makefiles.
b. We removed the typecasted NULL definitions such as
#define png_voidp_NULL (png_voidp)NULL
If you used these in your application, just use NULL instead.
c. We eliminated the PNG_1_0_X and PNG_1_2_X macros.
d. We eliminated the PNG_LEGACY_SUPPORTED macro.
e. We removed many WIN32_WCE #ifdefs.
f. We removed the functions png_read_init(info_ptr),
png_write_init(info_ptr), png_info_init(info_ptr),
png_read_destroy(), and png_write_destroy().
They have been deprecated since libpng-0.95.
g. We removed the png_permit_empty_plte() function. It has been
deprecated since libpng-1.0.9. Use png_permit_mng_features() instead.
h. We removed the obsolete stub functions png_get_mmx_flagmask(),
png_set_mmx_thresholds(), png_get_asm_flags(),
png_get_mmx_bitdepth_threshold(), png_get_mmx_rowbytes_threshold(),
png_set_asm_flags(), and png_mmx_supported()
i. We removed the obsolete png_check_sig(), png_memcpy_check(), and
png_memset_check() functions. Instead use !png_sig_cmp(),
png_memcpy(), and png_memset(), respectively, i.e.,
replace
png_check_sig(buf, 8)
with
png_sig_cmp(buf, 0, 8) == 0
replace
png_memcpy_check(png_ptr, dest, src, length)
with
png_memcpy(dest, src, length)
and replace
png_memset_check(png_ptr, dest, value, length)
with
png_memset(dest, value, length)
j. We removed support for global arrays to improve thread safety.
k. We removed support for numbered error messages by default, since we
never got around to actually numbering the error messages. The function
png_set_strip_error_numbers() was removed from the library by default.
l. The png_zalloc() and png_zfree() functions are no longer exported.
The png_zalloc() function no longer zeroes out the memory that it
allocates.
m. The function png_set_gray_1_2_4_to_8() was removed. It has been
deprecated since libpng-1.0.18 and 1.2.9, when it was replaced with
png_set_expand_gray_1_2_4_to_8() because the former function also
expanded palette images.
3. Several function prototypes were changed.
a. We changed the prototype for png_malloc() from
png_malloc(png_structp png_ptr, png_uint_32 size) to
png_malloc(png_structp png_ptr, png_alloc_size_t size)
b. We changed the prototypes of png_get_compression_buffer_size() and
png_set_compression_buffer_size() to work with png_size_t instead of
png_uint_32.
4. We added some new features:
a. We enabled iTXt chunk support by default. This changes the png_text
structure by adding the itxt_length, lang, and lang_key members.
b. We added the functions png_set_benign_errors(), png_benign_error(),
and png_chunk_benign_error(). With these, you can choose to treat
certain normally fatal errors as nonfatal.
c. Support for setting the maximum amount of memory that the application
will allocate for reading chunks was added, as a security measure.
The functions png_set_chunk_cache_max() and png_get_chunk_cache_max()
were added to the library.
d. We added the png_calloc() function and used it in place of
of "png_malloc(); png_memset();" except in the case in png_read_png()
where the array consists of pointers; in this case a "for" loop is used
after the png_malloc() to set the pointers to NULL, to give robust.
behavior in case the application runs out of memory part-way through
the process.
e. We implemented support for I/O states by adding png_ptr member io_state
and functions png_get_io_chunk_name() and png_get_io_state() in pngget.c
f. We added PNG_TRANSFORM_GRAY_TO_RGB to the available high-level
input transforms.
5. Other changes
a. We changed the names of the png_struct and info_struct members "trans"
and "trans_values" to "trans_alpha" and "trans_color", respectively.
b. Checking for and reporting of errors in the IHDR chunk is more thorough.
c. We removed the trailing '.' from the warning and error messages.
d. Direct access to png_ptr->jmpbuf has been deprecated since libpng
version 1.0.6, and libpng now generates a warning about it.
To avoid such warnings, change
setjmp(png_ptr->jmpbuf)
to
setjmp(png_jmpbuf(png_ptr))
