Bash惊现年度最大安全漏洞!-CSDN.NET



北京时间9月25日消息,Linux用户今天又得到了一个"惊喜"!Red Hat安全团队在 Linux 中广泛使用的Bash shell中发现了一个隐晦而危险的安全漏洞。该漏洞被称为"Bash Bug"或"Shellshock"。

当用户正常访问,该漏洞允许攻击者的代码像在Shell中一样执行,这就为各种各样的攻击打开了方便之门。而且,更糟糕的是,该漏洞已经在Linux中存在很长时间了,所以修补某个Linux机器很容易,但是要全部修补,几乎不可能实现。

Red Hat和Fedora已经发布了针对该漏洞的修补程序。该漏洞也会影响OS X,不过苹果公司尚未发布正式的修补程序。

这个Bash漏洞可能比Heartbleed更危险。

Red Hat的Robert David Graham比较了该漏洞和Heartbleed,发现前者分布更广泛,有可能对系统安全带来长期影响。Graham在一篇博客文章中写道:"有大量的软件以某种方式与Shell交互,我们没有办法列举出受该漏洞影响的所有软件。"据The Verge报道,Berkeley ICSI的研究员Nicholas Weaver也同意这个说法:"它很隐晦、很可怕,并且会伴随我们多年。"
