Buffer overflows occur when some sized portion of memory is overwritten with something bigger.. Marx Caesar S. . Barluado. Mishari. Rashid M. . Lucman. What is the study all about?. The study aims to determine whether crushed crab shells can be a potential pH buffer. Crushed crab shells contain calcium carbonate which is believed to be a potential pH buffer. Which then leads to production of cheaper buffers compared to commercial ones.. http://en.wikipedia.org/wiki/Stack_buffer_overflow. What is a stack buffer overflow?. Caused when a program writes more data to a buffer on the stack than what was initially allocated for the buffer. Topics Covered:. File Organization. Techniques of file organization. .
