 Buffer Overflow for Beginners

Infosecwriters brings us: Buffer Overflow for Beginners.

"Buffer overflows are a common vulnerability on all platforms, but are by far the most commonly exploited bug on the linux/unix Operating systems.
Commonly buffer overflows are exploited to change the flow in a programs execution, so that it points to a different memory address or overwrites crucial memory segments. If you know how memory is organised, you would know that on all x86 linux platforms, memory is organised in 4byte (32 bit) segments, consisting of a hex memory address, and will need to be converted to little endian byte ordering."
