liblivemedia: Multiple issues (4.3)
Last modified: 2019-03-20 12:57:36 CET
New Debian liblivemedia 2016.11.28-1+deb9u2 fixes: This update addresses the following issues: * 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. (CVE-2019-6256) * liblivemedia in Live555 before 2019.02.03 mishandles the termination of an RTSP stream after RTP/RTCP-over-RTSP has been set up, which could lead to a Use-After-Free error that causes the RTSP server to crash (Segmentation fault) or possibly have unspecified other impact. (CVE-2019-7314) * In Live555 before 2019.02.27, malformed headers lead to invalid memory access in the parseAuthorizationHeader function. (CVE-2019-9215)
