| Changes since the last public release (1.6.9): |
| |
| Version 1.6.10beta01 [February 9, 2014] |
| 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. |
