CVE-2007-2488
The IAX2 channel driver chaniax2 in Asterisk before 20070504 does not properly null terminate data, which allows remote attackers to trigger loss of transmitted data, and possibly obtain sensitive information memory contents or cause a denial of service application crash, by sending a frame that...

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...
DEBIAN-CVE-2007-2297
The SIP channel driver chansip in Asterisk before 1.2.18 and 1.4.x before 1.4.3 does not properly parse SIP UDP packets that do not contain a valid response code, which allows remote attackers to cause a denial of service crash...
Stack overflow
Multiple stack-based buffer overflows in the processsdp function in chansip.c of the SIP channel T.38 SDP parser in Asterisk before 1.4.3 allow remote attackers to execute arbitrary code via a long 1 T38FaxRateManagement or 2 T38FaxUdpEC SDP parameter in an SIP message, as demonstrated using SIP...

Null pointer dereference
The Manager Interface in Asterisk before 1.2.18 and 1.4.x before 1.4.3 allows remote attackers to cause a denial of service crash by using MD5 authentication to authenticate a user that does not have a password defined in manager.conf, resulting in a NULL pointer dereference...
