CVE-2018-14767

In Kamailio before 5.0.7 and 5.1.x before 5.1.4, a crafted SIP message with a double "To" header and an empty "To" tag causes a segmentation fault and crash. The reason is missing input validation in the "buildresbuffromsip_req" core function. This could result in denial of service and potentially the execution of arbitrary code.
