Integer Coercion Error

Description

Integer coercion refers to a set of flaws pertaining to the type casting, extension, or truncation of primitive data types.

Several flaws fall under the category of integer coercion errors. For the most part, these errors in and of themselves result only in availability and data integrity issues. However, in some circumstances, they may result in other, more complicated security related flaws, such as buffer overflow conditions.

Common Consequences

Scope: Availability

Impact: DoS: Resource Consumption (CPU), DoS: Resource Consumption (Memory), DoS: Crash, Exit, or Restart

Notes: Integer coercion often leads to undefined states of execution resulting in infinite loops or crashes.

Scope: Integrity, Confidentiality, Availability

Impact: Execute Unauthorized Code or Commands

Notes: In some cases, integer coercion errors can lead to exploitable buffer overflow conditions, resulting in the execution of arbitrary code.

Scope: Integrity, Other

Impact: Other

Notes: Integer coercion errors result in an incorrect value being stored for the variable in question.
