CWE-1045 带有虚拟析构函数的父类和没有虚拟析构函数的子类

Parent Class with a Virtual Destructor and a Child Class without a Virtual Destructor

结构: Simple

Abstraction: Variant

状态: Incomplete

被利用可能性: unkown

基本描述

A parent class has a virtual destructor method, but the parent has a child class that does not have a virtual destructor.

扩展描述

This issue can prevent the software from running reliably, since the child might not perform essential destruction operations. If the relevant code is reachable by an attacker, then this reliability problem might introduce a vulnerability, such as a memory leak (CWE-401).
