| buffer overflow |
|
Every program stores local variables, transfer parameters for functions, and return addresses for subprograms in the memory. If a program writes a character string that is too long to a local buffer variable, it overwrites the subsequent variables and possibly also the return address – resulting in a buffer overflow. In an attack using the buffer overflow, the over-long character string can contain codes that trigger activities on the attacked computer that can damage files, manipulate data, or make confidential information available to unauthorized persons, for example.
