-Subject: Fix integer overflow resulting in insufficient heap allocation
-
-IMAGE_DIMENSIONS_OK ensures that image width and height are less then
-46340, so that maximum number of pixels is ~2**31.
-
-Unfortunately, there are a lot of code that allocates image data with
-something like
-
-   malloc(w * h * sizeof(DATA32));
-
-Obviously, on 32-bit machines this results in integer overflow,
-insufficient heap allocation, with [massive] out-of-bounds heap
-overwrite.
-Either X_MAX should be reduced to 32767, or (w)*(h) should be checked to
-not exceed ULONG_MAX/sizeof(DATA32).
-
-Security implications:
-*) for 32-bit machines: insufficient heap allocation and heap overwrite
-in many image loaders, with escalation potential to remote code
-execution;
-*) for 64-bit machines: it seems, no impact.
