Asterisk RTP栈拒绝服务攻击漏洞
Vulnerability Description
Asterisk是开放源码的软件PBX，支持各种VoIP协议和设备。 Asterisk在RTP栈的STUN实现中存在拒绝服务漏洞。如果Asterisk在活动的RTP端口上接收到了特制的STUN报文的话，指针就可能超过可访问的内存。负责解析入站STUN报文的代码无法确认表示STUN属性的长度和STUN属性头大小是否超过了可用的数据，因此数据指针可能超过可访问的内存，导致崩溃。成功攻击要求启用了chan_sip、chan_gtalk、chan_jingle、chan_h323、chan_mgcp或chan_s
