CWE-128
Wrap-around Error
Wrap around errors occur whenever a value is incremented past the maximum value for its type and therefore "wraps around" to a very small, negative, or undefined value.
Mitigation
Phases:
Description:
- Requirements specification: The choice could be made to use a language that is not susceptible to these issues.
Mitigation
Phase: Architecture and Design
Description:
- Provide clear upper and lower bounds on the scale of any protocols designed.
Mitigation
Phase: Implementation
Description:
- Perform validation on all incremented variables to ensure that they remain within reasonable bounds.
CAPEC-92: Forced Integer Overflow
This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.
