Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (2.41%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

A Denial of Service issue was discovered in the LIVE555 Streaming Media libraries as used in Live555 Media Server 0.93. It can cause an RTSPServer crash in handleHTTPCmd_TunnelingPOST, when RTSP-over-HTTP tunneling is supported, via x-sessioncookie 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 in GroupsockHelper.cpp.
