Summary
In Eclipse ThreadX versions 6.0.1 through 6.5.2.202603, the Module Manager loaders take a module image without its length and trust the sizes and offsets in its preamble. A crafted module image can declare a code size larger than the image to read, or gain access to, the memory that follows it, and can place its entry points outside its code.
