92a7c79db2 [libpng16] Reject oversized iCCP profile length 
The code now validates the ICC profile length against the user chunk limit
before the buffer is allocated, as opposed to doing it while the buffer is read.

This removes the potential to consume virtual address space with a carefully
crafted ICC profile; only an issue on 32-bit systems where a valid profile can
be up to 2^32-4 bytes in length.  libpng never writes beyond the application
supplied limit, but previously it did allocate a buffer of the size specified in
the profile header.  The exploitability of this is almost zero; the address
space is released as soon as the PNG read completes.

Also clean up PNG_DEBUG compile of pngtest.c.

19fefd3a4b [libpng16] Return NULL from png_malloc_array() with a warning instead of calling 
png_error() on failure.  Reject oversized iCCP profile immediately.

f9e37f54eb [libpng16] Worked around rgb-to-gray issues in libpng 1.6. The previous 
attempts to ignore the errors in the code aren't quite enough to
deal with the 'channel selection' encoding added to libpng 1.7; abort.

Glenn Randers-Pehrson
01a0e8062d [libpng16] Reverted addition of png_set_filler_16 and png_set_add_alpha_16() 
functions. They unnecessarily duplicate png_set_filler() and png_set_add_alpha()
which now work properly with 16-bit images.
 2015-09-24 22:39:53 -05:00
Glenn Randers-Pehrson
efe4e5d10d [libpng16] Reverted the fix of byte order in png_do_read_filler() with 16-bit 
input that was made in version 1.6.17beta01, to preserve legacy
behavior even though it was incorrect.  Instead, added new API
png_set_filter_16() and png_set_add_alpha_16() that set a flag to
make png_do_read_filter() interpret the filler bytes properly.

John Bowler
2d62f7406f [libpng16] Fixed the recently reported 1's complement security issue by 
replacing the value that is illegal in the PNG spec, in both signed and
unsigned values, with 0. Illegal unsigned values (anything greater than or equal
to  0x80000000) can still pass through, but since these are not illegal
in ANSI-C (unlike 0x80000000 in the signed case) the checking that
occurs later can catch them (John Bowler).

John Bowler
751cee5ef1 [libpng16] Added signed/unsigned 16-bit safety net. This removes the dubious 
0x8000 flag definitions on 16-bit systems. They aren't supported
yet the defs *probably* work, however it seems much safer to do this
and be advised if anyone, contrary to advice, is building libpng 1.6
on a 16-bit system. It also adds back various switch default clauses
for GCC; GCC errors out if they are not present (with an appropriately
high level of warnings).

f6e7551f06 [libpng16] Eliminated the final two Coverity defects (insecure temporary file 
handling in contrib/libtests/pngstest.c; possible overflow of
unsigned char in contrib/tools/png-fix-itxt.c). To use the "secure"
file handling, define PNG_USE_MKSTEMP, otherwise "tmpfile()" will
continue to be used.

b26b51d154 [libpng16] Quieted Coverity issues in pngfix.c, png-fix-itxt.c, pngvalid.c,

25bfb13770 [libpng16] Removed non-working progressive reader 'skip' function. This 
function has apparently never been used. It was implemented
to support back-door modification of png_struct in libpng-1.4.x
but was apparently never tested (because it does nothing and cannot
do anything).

89edbf8317 [libpng16] Removed WRITE_WEIGHTED_FILTERED code, to save a few kbytes of the

tell, no one uses it. The png_set_filter_heuristics() and
png_set_filter_heuristics_fixed() APIs are retained but deprecated
and do nothing.
