• Buffer overflow
  Buffer overflow
  In computer security and programming, a buffer overflow, or buffer overrun, is an anomaly where a program, while writing data to a buffer, overruns the buffer's boundary and overwrites adjacent memory. This is a special case of violation of memory safety....
  
  , a situation whereby the incoming data size exceeds that which can be accommodated by a buffer
• Stack overflow
  Stack overflow
  In software, a stack overflow occurs when too much memory is used on the call stack. The call stack contains a limited amount of memory, often determined at the start of the program. The size of the call stack depends on many factors, including the programming language, machine architecture,...
  
   in which a computer program makes too many subroutine calls and its call stack runs out of space
• Heap overflow
  Heap overflow
  A heap overflow is a type of buffer overflow that occurs in the heap data area. Heap overflows are exploitable in a different manner to that of stack-based overflows. Memory on the heap is dynamically allocated by the application at run-time and typically contains program data...
  
  
• Arithmetic overflow
  Arithmetic overflow
  The term arithmetic overflow or simply overflow has the following meanings.# In a computer, the condition that occurs when a calculation produces a result that is greater in magnitude than that which a given register or storage location can store or represent.# In a computer, the amount by which a...
  
  , a condition that occurs when a calculation produces a result that is greater than what a given register can store or represent
• Overflow condition, a situation that occurs when more information is being transmitted than the hardware can handle

Water

• Overflow, A situation observed on frozen rivers when the water flowing beneath the ice seeps up through cracks in the ice. Occurs as the ice cover on the river thickens, freezing steadily downward toward the river bed, and the space available for water to flow is decreased, causing increased flow velocities and pressure. Overflow and the patches of open water and wet snow associated with it are problematic for travel on rivers in cold climates.

• Sanitary sewer overflow
  Sanitary sewer overflow
  Sanitary sewer overflow is a condition whereby untreated sewage is discharged into the environment prior to reaching treatment facilities thereby escaping wastewater treatment. When caused by rainfall it is also known as wet weather overflow. It is primarily meaningful in developed countries,...
