DescriptionThis test case checks if the taint source is less than 20 characters, and if so, allocates a buffer on the heap with 20 characters. It sets the buffer to all 0's, then calls realpath on the taint source, with the destination being the 20-character heap buffer. If realpath evaluates to more than 20 characters, it will over-write memory reserved for the memory manager, resulting in a glibc error when the heap buffer is freed.
- Base program: Tree
