version 1.0.57 [February 18, 2012] version 1.0.57 [March 8, 2012]
Updated contrib/pngminus/makefile.std (Samuli Souminen) Removed two useless #ifdef directives from pngread.c and one from pngrutil.c
Fixed CVE-2011-3026 buffer overrun bug. Eliminated redundant png_push_read_tEXt|zTXt|iTXt|unknown code from
pngpread.c and use the sequential png_handle_tEXt, etc., in pngrutil.c;
now that png_ptr->buffer is inaccessible to applications, the special
handling is no longer useful.
Fixed bug with png_handle_hIST with odd chunk length (Frank Busse).
Fixed incorrect type (int copy should be png_size_t copy) in png_inflate().
Fixed off-by-one bug in png_handle_sCAL() when using fixed point arithmetic,
causing out-of-bounds read in png_set_sCAL() because of failure to copy
the string terminators. This bug was introduced in libpng-1.0.6 (Frank
Busse).
Removed the png_free() of unused png_ptr->current_text from pngread.c.
Added libpng license text to pnggccrd.c and pngvcrd.c (requested by Chrome).
Removed all of the assembler code from pnggccrd.c and just "return 2;".
