CWE-466: Return of Pointer Value Outside of Expected Range

Weakness ID: 466
Abstraction: Base
Structure: Simple
Status: Draft
Presentation Filter:
+ Description
A function can return a pointer to memory that is outside of the buffer that the pointer is expected to reference.
+ Relationships

The table(s) below shows the weaknesses and high level categories that are related to this weakness. These relationships are defined as ChildOf, ParentOf, MemberOf and give insight to similar items that may exist at higher and lower levels of abstraction. In addition, relationships such as PeerOf and CanAlsoBe are defined to show similar weaknesses that the user may want to explore.

+ Modes Of Introduction

The different Modes of Introduction provide information about how and when this weakness may be introduced. The Phase identifies a point in the software life cycle at which introduction may occur, while the Note provides a typical scenario related to introduction during the given phase.

+ Common Consequences

The table below specifies different individual consequences associated with the weakness. The Scope identifies the application security area that is violated, while the Impact describes the negative technical impact that arises if an adversary succeeds in exploiting this weakness. The Likelihood provides information about how likely the specific consequence is expected to be seen relative to the other consequences in the list. For example, there may be high likelihood that a weakness will be exploited to achieve a certain impact, but a low likelihood that it will be exploited to achieve a different impact.

Maintenance

This entry should have a chaining relationship with CWE-119 instead of a parent / child relationship, however the focus of this weakness does not map cleanly to any existing entries in CWE. A new parent is being considered which covers the more generic problem of incorrect return values. There is also an abstract relationship to weaknesses in which one component sends incorrect messages to another component; in this case, one routine is sending an incorrect value to another.
