CVE-2007-1693
The SIP channel module in Yet Another Telephony Engine Yate before 1.2.0 sets the callerinfouri parameter using an incorrect variable that can be NULL, which allows remote attackers to cause a denial of service NULL dereference and application crash via a Call-Info header without a purpose...

CVE-2007-1693
The CVE-2007-1693 issue affects Yet Another Telephony Engine (Yate) before version 1.2.0. The SIP channel module reads the Call-Info header and uses the header’s purpose parameter to set caller_info_uri; a programming error causes a NULL dereference when the purpose param is missing, allowing rem...

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...

CVE-2007-2293
Asterisk’s SIP channel T.38 SDP parser (chan_sip.c) contains multiple stack-based buffer overflows in process_sdp, exploitable by long T38FaxRateManagement or T38FaxUdpEC SDP parameters in SIP INVITE messages. Affected are Asterisk versions before 1.4.3. Exploitation allows remote code execution;...
CVE-2007-2297
CVE-2007-2297 affects the SIP channel driver (chan_sip) in Asterisk prior to 1.2.18 and 1.4.x prior to 1.4.3. The vulnerability arises from improper parsing of SIP UDP packets that do not contain a valid response code, allowing remote attackers to cause a denial of service (crash). Public details...
