Heap based buffer overflow in vim/vim 9.0.0946 and below by allowing an attacker to CTRL-W gf in the expression used in the RHS of the substitute command.
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.
