Asterisk SIP T.38 SDP解析远程栈溢出漏洞

Asterisk是一款PBX系统的软件，运行在Linux系统上，支持使用SIP、IAX、H323协议进行IP通话。 Asterisk的SIP/SDP处理器中存在多个远程栈溢出漏洞，远程攻击者可能利用此漏洞控制服务器。 如果所发送SIP报文中的SDP数据包含有超长的T38参数的话，就可以触发这个溢出，导致执行任意代码。这个漏洞是由chansip.c文件中的processsdp函数调用sscanf所导致的： else if sscanfa, "T38FaxRateManagement:%s", s == 1 found = 1; if optiondebug 2 astlogLOGDEBUG...
