Buffer overflow is a kind of exception specific to the field of computing. A buffer overflow occurs when a program attempts to put more data into a buffer, exceeding the capacity of the buffer. As a result, the data overflows from the allocated memory of the buffer and overwrites the data...
You can also protect against buffer overflows by using an extension of a compiler that usescanaries. The canaries are special values that the compiler places on the stack between the location of the buffer and the location of control data. When a buffer overflow occurs, it is the canary that...
A buffer overflow occurs when a program or process attempts to write more data to a fixed-length block of memory, or buffer, than the buffer is allocated to hold. Buffers contain a defined amount of data; any extra data will overwrite data values in memory addresses adjacent to the destinat...

In the below example, we will create a StringStream object as we have created in the previous section. We will then use a buffer, a while loop, and a for loop to print the content of the StringStream object in the form of arrays of string. The code will check if the stream is ...
The value is 0 for SNMPv1 or 1 for SNMPv2c. Community name: is used for authentication between the SNMP agent and NMS. The value is a user-defined string of characters. The community name can be read or write. When SNMP get operations are performed, the read community name is used ...
A clean buffer is a data page in memory that is NOT MODIFIED. Modified buffers that havenotbeen written to disk are termedDIRTYbuffers and are typically written to disk by checkpoint processing. DBCC DROPCLEANBUFFERS removes the UNMODIFIED buffers from the buffer pool (no longer has...
