Asterisk IAX2报文放大远程拒绝服务漏洞

BUGTRAQ ID: 28901 CVECAN ID: CVE-2008-1897 Asterisk是开放源码的软件PBX，支持各种VoIP协议和设备。 Asterisk在处理呼叫的机制上存在漏洞，远程攻击者可能利用此漏洞对第三方机器执行拒绝服务攻击。 IAX2协议允许ICNEW报文启动呼叫。ICNEW报文是18字节长的UDP报文，而呼叫可能非常长，包含有很多数据。由于UDP是可以伪造的，因此远程攻击者可以在IAX2握手期间欺骗IAX2握手，导致Asterisk服务器向目标发送大量数据，造成网络堵塞。 Asterisk Asterisk 1.4.x Asterisk Asterisk...
