What happens when a buffer recievs more data than it can hold ?
-
The excess data is bounced back to the senders Network, causing it to crash
-
The excess data is abosrbed into the reciepient network, causing it to slowdown
-
The excess data overflows into the adjacent buffers, corrupting or overwriting the valid data held in them
-
The excess data is removed by the compiler usually
When a buffer receives more data than its allocated capacity, the excess data overflows into adjacent memory locations, corrupting or overwriting whatever valid data or instructions are stored there. This is a buffer overflow vulnerability. Attackers can exploit this by carefully crafting the excess data to overwrite return addresses or inject malicious code, potentially taking control of the program. The other options are incorrect: buffers are physical memory allocations with no bounce-back mechanism, data is not absorbed by networks, and compilers do not automatically remove excess data at runtime.
