SerialiseValue in RenderDoc before 1.27 allows an Integer Overflow with a resultant Buffer Overflow. 0xffffffff is sign-extended to 0xffffffffffffffff (SIZE_MAX) and then there is an attempt to add 1.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
