What is a buffer overflow attack and how does one work? Exploiting a buffer overflow allows an attacker to control or crash a process or to modify its internal variables. Buffer overflow always ranks high in the Common Weakness Enumeration (CWE) andSANS Top 25 Most Dangerous Software Errors. ...
(FIFO) data structure used to store data that is required for a long time during program running. When the heap overflows, even if the program does not stop execution immediately, the program may be unstable or even crash. In malicious attacks, attackers may use heap buffer overflow to ...

(The analogy breaks down a bit here, because you pens don't work that way in real life, but computer memory does) You pay someone a $500 deposit on a $5000 car, so you now owe them $4500. They tell you their name is John Smith. You write the amount (4500) and the name (...

because strcpy does not actually check whether the destination buffer has sufficient space for the data to be copied. Therefore, when you call strcpy(x, y); with x = malloc(0); the strcpy function simply tries to copy the contents of the source string y to the destination buffer pointed ...

Buffer Overflow This is the bug that got me interested in strtod(). I had been studying the decimal to floating-point conversion routines of gcc and glibc when this security flaw became big news. I was struck by how many projects used it, and how such a well-worn piece of code could ...
