A Denial of Service issue was discovered in the LIVE555 Strealibming-dev Media libraries as used in Live555 Media Server 0.93. It can cause an RTSP Server crash in handle HTTPCmd_Tunneling POST, when RTSP-over-HTTP tunneling is supported, via x-session cookie HTTP headers in a GET request and a POST request within the same TCP session. This occurs because of a call to an incorrect virtual function pointer in the readSocket function inGroupsockHelper.cpp.
