界: Input Validation and Representation
输入验证与表示问题是由元字符、交替编码和数字表示引起的。安全问题源于信任输入。这些问题包括：“Buffer Overflows”、“Cross-Site Scripting”攻击、“SQL Injection”等其他问题。
Denial of Service: Stack Exhaustion
Abstract
攻击者可以输入经特殊技术处理的数据来修改或定义程序的数据结构实现，从而可能因堆栈耗尽而导致 Denial of Service 攻击。
Explanation
程序直接用于修改或定义其数据结构实现的用户指定数据可能容易受到堆栈耗尽的影响。例如，如果用户可以在递归处理的链接数据结构中创建循环链接，这可能会导致无限递归，从而导致堆栈耗尽。
示例 1：以下代码片段使用 Apache Log4j2 演示了此漏洞。
该小程序允许用户将
示例 1：以下代码片段使用 Apache Log4j2 演示了此漏洞。
Marker child = MarkerManager.getMarker("child");
Marker parent = MarkerManager.getMarker("parent");
child.addParents(MarkerManager.getMarker(userInput));
parent.addParents(MarkerManager.getMarker(userInput2));
String toInfinity = child.toString();
该小程序允许用户将
child 和 parent 的父标记设置为用户定义的标记。如果用户将 child 的父标记设置为 parent，将 parent 的父标记设置为 child，则会在标记数据结构中创建一个循环链接。在包含循环链接的数据结构上运行递归 toString 方法时，程序会抛出堆栈溢出异常并崩溃。这会因堆栈耗尽而导致 Denial of Service 攻击。References
