Asterisk IAX2呼叫号码耗竭拒绝服务漏洞

Asterisk是一款开放源码的软件PBX，支持各种VoIP协议和设备。 Asterisk不正确处理消息中的呼叫号码字段数据，远程攻击者可以利用漏洞对服务程序进行拒绝服务攻击。 IAX2协议使用呼叫号码关联相关的消息，但是协议定义消息中的呼叫号码字段仅为15位的固定大小字段。因此，如果所有呼叫号码使用完后，就无法处理更多的会话。 呼叫号码在IAX2消息交换开始时建立，攻击者可以发送大量消息，消耗完所有的呼叫号码空间。由于呼叫号码被指派前不需要三次握手处理，因此攻击者也可能使用伪造的源IP地址。 Asterisk 1.x Asterisk Business Edition 2.x...
