Every once in a while (when I think out loud and people overhear me) I am forced to explain what a buffer overflow is. Because I can't really think of a good metaphor, I end up spending about 10 minutes explaining how (vulnerable) programs work and memory allocation, and then have ab...
A buffer overflow can occur inadvertently or when a malicious actor causes it. A threat actor can send carefully crafted input -- referred to asarbitrary code-- to a program. The program attempts to store the input in a buffer that isn't large enough for the input. If the excess data i...
the program stops execution immediately and displays a corresponding error message. Stack overflow attacks are the most common type of buffer overflow attacks. For a stack overflow attack to be carried out, programs must write data to the stack and the size of the written data must not be cont...
A buffer overflow or overrun is a memory safety issue where a program does not properly check the boundaries of an allocated fixed-length memory buffer and writes more data than it can hold. This causes data to overflow to adjacent memory space, overwrit

The socket size has been set to 2 MB. When the reader cannot read fast enough the socket "overflows", i.e. packets are dropped from the buffer. What I would like to know is how the Linux kernel drops packets out of the socket buffer. I assume that the socket buffer itself is a ...
A buffer overflow can be: Accidental.You try to do too much within one program, and you exceed the space the program gives you. The program may begin to behave erratically, and in some cases, it may stop working altogether. Intentional.Someone sends in data that's too large for your pro...
