Array Index Out Of Bounds

Reports array or pointer variable access expressions where index may be out of bounds of an array or allocated buffer.

Example:

  void foo() {
      int buffer[100];

      for (int i = 0; i <= 100; i ++)
          buffer[i] = 0; // buffer overflow when i is equal to 100
  }
