Growing the stack up[edit]

I removed an uncited assertion that growing the stack in the opposite direction would reduce the risk of a buffer overflow. This is incorrect, see [1] for a description of how this is done (article on how to exploit stack overflows on HP-UX PA-RISC machines, which grow the stack up)...see Stack buffer overflow for further explanation of why this is not true. Also, there was an assertion that it was the operating system, and not the hardware the determines which direction the stack grows. There are some processors that allow for a software defined direction that the stack grows, but ultimately this is done by the hardware, and in almost every case, it is not an option available to the operating system to change. --Michael Lynn 02:05, 16 August 2007 (UTC) Added Manojkumar.R.S (talk) 07:57, 4 October 2011 (UTC)[reply]
