界: Errors
错误和错误处理代表一类 API。与错误处理相关的错误非常普遍，因此它们应该拥有自己的专属章节。与“API 滥用”一样，有两种情况可以引入与错误相关的安全漏洞：最常见的一种是错误处理不当（或者根本不处理）。第二种是产生错误，这些错误要么（向潜在的攻击者）泄露过多信息，要么难以处理。
Poor Error Handling: Empty Catch Block
Abstract
忽略异常会导致程序无法发现意外状况和情况。
Explanation
几乎每一次对软件系统的严重攻击都是从违反程序员的假设开始的。攻击发生后，程序员的假设似乎站不住脚，缺乏依据。但在攻击发生之前，许多程序员会在午休时间过后为他们的种种假设做很好的辩护。
在代码中，很容易发现两个令人怀疑的假设：“此方法调用绝不可能出错”和“此调用即使出错也不要紧”。当程序员忽略异常时，这也就隐式地表明他们是基于上述这些假设之一进行的操作。
示例 1：以下代码摘录将忽略

在代码中，很容易发现两个令人怀疑的假设：“此方法调用绝不可能出错”和“此调用即使出错也不要紧”。当程序员忽略异常时，这也就隐式地表明他们是基于上述这些假设之一进行的操作。
示例 1：以下代码摘录将忽略
doExchange() 中很少抛出的异常。
try {
doExchange();
}
catch (RareException e) {
// this can never happen
}
如果抛出
RareException，程序将继续执行，就像未发生任何异常情况。该程序未记录表明特殊情况的任何证据，这可能会导致以后无法解释该程序的行为。References

Explanation
几乎每一个对软件系统的严重攻击都是从违反程序员的假设开始的。攻击后，程序员的假设看起来既脆弱又拙劣，但攻击前，许多程序员会在午休时间为自己的种种假设做很好的辩护。
在代码中，很容易发现两个令人怀疑的假设：“一是这个方法调用不可能出错；二是即使出错了，也不会对系统造成什么重要影响。”因此当程序员忽略异常时，这其实就表明了他们是基于上述假设进行的操作。

在代码中，很容易发现两个令人怀疑的假设：“一是这个方法调用不可能出错；二是即使出错了，也不会对系统造成什么重要影响。”因此当程序员忽略异常时，这其实就表明了他们是基于上述假设进行的操作。
例 1：下面摘录的代码会忽略一个由
open() 抛出的罕见异常。
try:
f = open('myfile.txt')
s = f.readline()
i = int(s.strip())
except:
# This will never happen
pass
如果抛出
RareException 异常，程序会继续执行，就像什么都没有发生一样。程序不会记录任何有关这一特殊情况的依据，因而事后再查找这一异常就可能很困难。References
