Heap Buffer Overflow in iterate_chained_fixups in GitHub repository radareorg/radare2 prior to 5.6.6.
A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
The product writes data past the end, or before the beginning, of the intended buffer.
