|
|
Changes since the last public release (1.6.9):
|
|
Backported changes from libpng-1.7.0beta30 and beta31:
|
|
Fixed a large number of instances where PNGCBAPI was omitted from
|
|
function definitions.
|
|
Added pngimage test program for png_read_png() and png_write_png()
|
|
with two new test scripts.
|
|
Removed dependence on !PNG_READ_EXPAND_SUPPORTED for calling
|
|
png_set_packing() in png_read_png().
|
|
Fixed combination of ~alpha with shift. On read invert alpha, processing
|
|
occurred after shift processing, which causes the final values to be
|
|
outside the range that should be produced by the shift. Reversing the
|
|
order on read makes the two transforms work together correctly and mirrors
|
|
the order used on write.
|
|
Do not read invalid sBIT chunks. Previously libpng only checked sBIT
|
|
values on write, so a malicious PNG writer could therefore cause
|
|
the read code to return an invalid sBIT chunk, which might lead to
|
|
application errors or crashes. Such chunks are now skipped (with
|
|
chunk_benign_error).
|
|
Make png_read_png() and png_write_png() prototypes in png.h depend
|
|
upon PNG_READ_SUPPORTED and PNG_WRITE_SUPPORTED.
|
|
Support builds with unsupported PNG_TRANSFORM_* values. All of the
|
|
PNG_TRANSFORM_* values are always defined in png.h and, because they
|
|
are used for both read and write in some cases, it is not reliable
|
|
to #if out ones that are totally unsupported. This change adds error
|
|
detection in png_read_image() and png_write_image() to do a
|
|
png_app_error() if the app requests something that cannot be done
|
|
and it adds corresponding code to pngimage.c to handle such options
|
|
by not attempting to test them.
|
|
Moved redefines of png_error(), png_warning(), png_chunk_error(),
|
|
and png_chunk_warning() from pngpriv.h to png.h to make them visible
|
|
to libpng-calling applications.
|
|
Moved OS dependent code from arm/arm_init.c, to allow the included
|
|
implementation of the ARM NEON discovery function to be set at
|
|
build-time and provide sample implementations from the current code in the
|
|
contrib/arm-neon subdirectory. The __linux__ code has also been changed to
|
|
compile and link on Android by using /proc/cpuinfo, and the old linux code
|
|
is in contrib/arm-neon/linux-auxv.c. The new code avoids POSIX and Linux
|
|
dependencies apart from opening /proc/cpuinfo and is C90 compliant.
|
|
Check for info_ptr == NULL early in png_read_end() so we don't need to
|
|
run all the png_handle_*() and depend on them to return if info_ptr == NULL.
|
|
This improves the performance of png_read_end(png_ptr, NULL) and makes
|
|
it more robust against future programming errors.
|
|
Check for __has_extension before using it in pngconf.h, to
|
|
support older Clang versions (Jeremy Sequoia).
|
|
Treat CRC error handling with png_set_crc_action(), instead of with
|
|
png_set_benign_errors(), which has been the case since libpng-1.6.0beta18.
|
|
Use a user warning handler in contrib/gregbook/readpng2.c instead of default,
|
|
so warnings will be put on stderr even if libpng has CONSOLE_IO disabled.
|
|
Added png_ptr->process_mode = PNG_READ_IDAT_MODE in png_push_read_chunk
|
|
after recognizing the IDAT chunk, which avoids an infinite loop while
|
|
reading a datastream whose first IDAT chunk is of zero-length.
|
|
This fixes CERT VU#684412 and CVE-2014-0333.
|
|
Don't recognize known sRGB profiles as sRGB if they have been hacked,
|
|
but don't reject them and don't issue a copyright violation warning.
|
|
Moved some documentation from png.h to libpng.3 and libpng-manual.txt
|
|
Minor editing of contrib/arm-neon/README and contrib/examples/*.c
|
|
Fixed typos in the manual and in scripts/pnglibconf.dfa (CFLAGS -> CPPFLAGS
|
|
and PNG_USR_CONFIG -> PNG_USER_CONFIG).
|
|
Un-deprecated png_data_freer().
