This makes it possible to subvert the program or system or cause it to crash. The stack, also called a pushdown stack or first-in last-out circuit, is a form of buffer that holds the intermediate results of an operation or data that is awaiting processing. If the stack receives more data than it can hold, the excess data is lost. Some of this data may be critical to system operation. A skilled hacker can corrupt or change critical data by deliberately introducing too much data into the stack. ______________________ SELECTED LINKS: Hiroaki Etoh and Kunikasu Yoda of IBM (Tokyo) discuss methods of protecting systems from stack smashing. http://www.trl.ibm.com/projects/security/ssp/main.html ______________________ RELATED TERMS: stack http://whatis.techtarget.com/definition/0,,sid9_gci213047,00.html buffer http://whatis.techtarget.com/definition/0,,sid9_gci211713,00.html ______________________ TODAY'S TECH NEWS: MAJOR SITES SURVIVE DEFACEMENT CHALLENGE Experts aren't ready to declare this weekend's defacement challenge a bust, but said administrators heeded last week's warnings and locked down their systems. http://searchsecurity.techtarget.com/originalContent/0,289142,sid14_gci913460,00.html ONYX, PIVOTAL MAKE CRM FAST AND FURIOUS Call it CRM without the wait.
