libpng: update 1.6.19 -> 1.6.20 (CVE-2015-8126)
Version 1.6.20beta01 [November 20, 2015] Avoid potential pointer overflow/underflow in png_handle_sPLT() and png_handle_pCAL() (Bug report by John Regehr). Version 1.6.20beta02 [November 23, 2015] Fixed incorrect implementation of png_set_PLTE() that uses png_ptr not info_ptr, that left png_set_PLTE() open to the CVE-2015-8126 vulnerability. Version 1.6.20beta03 [November 24, 2015] Backported tests from libpng-1.7.0beta69. Version 1.6.20rc01 [November 26, 2015] Fixed an error in handling of bad zlib CMINFO field in pngfix, found by American Fuzzy Lop, reported by Brian Carpenter. inflate() doesn't immediately fault a bad CMINFO field; instead a 'too far back' error happens later (at least some times). pngfix failed to limit CMINFO to the allowed values but then assumed that window_bits was in range, triggering an assert. The bug is mostly harmless; the PNG file cannot be fixed. Version 1.6.20rc02 [November 29, 2015] In libpng 1.6 zlib initialization was changed to use the window size in the zlib stream, not a fixed value. This causes some invalid images, where CINFO is too large, to display 'correctly' if the rest of the data is valid. This provides a workaround for zlib versions where the error arises (ones that support the API change to use the window size in the stream). Version 1.6.20 [December 3, 2015] No changes.
