Examples of Unicode overflows include Code Red, a devastating Trojan with an estimated economic cost in the billions of dollars. If relying upon operating system functions or utilities written in a vulnerable language, ensure that they: use the principle of least privilege use compilers that protect against stack and heap overflows are current in terms of patches Integer Overflow When an application takes two numbers of fixed word size and perform an operation with them, the result may not fit within the same word size.
Integer overflows can be a problem in any language and can be exploited when integers are used in array indices and implicit short math operations.
How to determine if you are vulnerable Examine use of signed integers, bytes, and shorts. How would your program react to a negative or zero value for integer values, particular during array lookups?
How to protect yourself If using. Otherwise, use a "BigInteger" or "BigDecimal" implementation in cases where it would be hard to validate input yourself.
If your compiler supports the option, change the default for integers to be unsigned unless otherwise explicitly stated.
Use unsigned integers whenever you don't need negative values. Use range checking if your language or framework supports it, or be sure to implement range checking yourself after all arithmetic operations.
