CVE-2019-6256

CRITICAL

Live555 Media Server 0.93 - Denial of Service via RTSP-over-HTTP Tunneling x-sessioncookie Header

Title source: llm
STIX 2.1

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.
