Ubuntu 16.04 ESM / 18.04 ESM : liveMedia vulnerabilities (USN-4853-1)

critical Nessus Plugin ID 183646

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4853-1 advisory.

 - An exploitable code execution vulnerability exists in the HTTP packet-parsing functionality of the LIVE555 RTSP server library version 0.92. A specially crafted packet can cause a stack-based buffer overflow, resulting in code execution. An attacker can send a packet to trigger this vulnerability. (CVE-2018-4013)

 - 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)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
