名称: Deletion of Data Structure Sentinel

The accidental deletion of a data-structure sentinel can cause serious programming logic problems.

CWE 描述

Often times data-structure sentinels are used to mark structure of the data structure. A common example of this is the null character at the end of strings. Another common example is linked lists which may contain a sentinel to mark the end of the list. It is dangerous to allow this type of control data to be easily accessible. Therefore, it is important to protect from the deletion or modification outside of some wrapper interface which provides safety.

注意: If a control character, such as NULL is removed, one may cause resource access control problems.

潜在缓解措施

Phases : Architecture and Design
Use an abstraction library to abstract away risky APIs. Not a complete solution.
Phases : Build and Compilation
Phases : Operation
Use OS-level preventative functionality. Not a complete solution.

漏洞映射说明

依据 : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
备注 : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
