Copying data in to a buffer that is not large enough to hold that data results in a buffer overflow. While not limited to Null Terminated Byte Strings (NTBS), this type of error often occurs when manipulating NTBS data. To prevent such errors, limit copies either through truncation (although consult \[[STR03-A. Do not inadvertently truncate a NULL null-terminated byte string]] for problems that may cause) or, preferably, ensure that the destination is of sufficient size to hold the character data to be copied and the NULL-termination character. |
