HuffmanTree_makeFromFrequencies in lodepng.c in LodePNG through 2019-09-28, as used in WinPR in FreeRDP and other products, has a memory leak because a supplied realloc pointer (i.e., the first argument to realloc) is also used for a realloc return value.

Weakness

The product does not check the return value from a method or function, which can prevent it from detecting unexpected states and conditions.
