stb_image: Overflow checking for image allocs.
...
Adds some helpers that check whether a product of multiple
factors (that need to be non-negative: this is enforced)
summed with another non-negative value overflows when
performed as int. Since stb_image mostly works in ints,
this seems like the safest route. Limits size of images
to 2GB but several of the decoders already enforce this
limit (or even lower ones).
Also adds wrappers for malloc that combine a mul-add-with-
overflow-check with the actual malloc, and return NULL
on failure. Then use them when allocating something that
is the product of multiple factors.
For image formats, also add a top-level "is this too big?"
check that gives a more useful error message; otherwise,
the failed mallocs result in an "out of memory" error.
The idea is that the top-level checks should be the primary
way to catch these bugs (and produce a useful error message).
But a misleading error message is still vastly preferable to
a buffer overflow exploit.
Fixes issues #310 , #313 , #314 , #318 . (Verified with the
provided test images)
Along the way, this fixes a previously unnoticed bug in
ldr_to_hdr / hdr_to_ldr (missing NULL check); these functions
are called with the result of an image decoder, so NULLs can
definitely happen.
Another bug noticed along the way is that handling of
interlaced 16-bit PNGs was incorrect. Fixing this (along
with the previous modifications) fixes issue #311 .
Yet another bug noticed during this change is that reduce_png
did not check the right pointer during its out of memory
check. Fix that too.
