The APNG patch for v1.6.47 isn't out yet, so I hacked in some changes to get the APNG code to build in pngrutil.c. In particular, the PNGv3 chromacity changes also modified pngrutil.c to use table-based dispatch instead of an if/else. png_read_frame_head() doesn't use this yet, so the APNG functions in pngrutil.c haven't been marked static yet, but they do now return png_handle_result_code. TODO: Rebase using the APNG patch once it's rebased for v1.6.47. NOTE: PNGv3 apparently makes APNG part of the specification, so libpng "should" gain built-in support for APNG without a patch at some point.

Changes from version 1.6.46 to version 1.6.47
|
|
---------------------------------------------
|
|
|
|
* Modified the behaviour of colorspace chunks in order to adhere
|
|
to the new precedence rules formulated in the latest draft of
|
|
the PNG Specification.

|
|
* Fixed a latent bug in `png_write_iCCP`.
|
|
This would have been a read-beyond-end-of-malloc vulnerability,
|
|
introduced early in the libpng-1.6.0 development, yet (fortunately!)
|
|
it was inaccessible before the above-mentioned modification of the
|
|
colorspace precedence rules, due to pre-existing colorspace checks.
