This can be a problem when the allocated size of the affected buffer is too small and the current depth of the stack is shallow (i.e., there is not much space from the end of the current stack frame to the start of the stack). Despite its problems, the NOP-sled is often the only method that will work for a given platform, environment, or situation, and as such it is still an important technique.
This can be a challenge when the assigned space of the impacted buffer is too limited and the current depth of the stack is shallow (i.e., there is not much room from the end of the current stack frame to the beginning of the stack). Despite its issues, the NOP-sled is often the sole viable approach for a specific platform, environment, or circumstance, making it still an essential technique.
