界: API Abuse

API 是调用方和被调用方之间的约定。最常见的 API 滥用是由于调用方未能遵守此约定的终止导致的。例如，如果某个程序在调用 chroot() 后未能调用 chdir()，则违反了用于指定如何安全地更改活动根目录的约定。库滥用的另一个典型示例是期望被调用方向调用方返回可信的 DNS 信息。在这种情况下，调用方通过对被调用方行为做出某种假设（返回值可用于身份验证目的）滥用其 API。另一方也可能违反调用方-被调用方约定。例如，如果编码器子类化 SecureRandom 并返回一个非随机值，则将违反此约定。

Often Misused: Exception Handling

C/C++

Abstract

_alloca() 函数会抛出一个堆栈溢出异常，可能造成程序的崩溃。

Explanation

_alloca() 函数在堆栈上分配存储空间。如果分配请求对于可用的堆栈空间来说太大，_alloca() 将会抛出一个异常。如果未能捕获到异常，程序将会崩溃，并有可能引起 denial of service 攻击。

在 Microsoft Visual Studio 2005(R) 中，_alloca() 已经被淘汰。它已由更加安全的 _alloca_s() 所取代。
