The following example allocates space for a key using malloc then uses strcpy() to place the key there. ice age 5 und 6 by using calloc(), as the call to strcpy() does it. The memory allocated to a destination should be large enough to copy the source string (including the terminating null character). The pointer to the memory that is passed to strcpy is never saved anywhere and the compiler can therefore prove that it is leaked. … A buffer overflow vulnerability occurs when data can be written outside the memory allocated for a buffer, either past the end or before the beginning which dynamically allocates enough … Notes.
