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.

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.

    It was discovered that liveMedia incorrectly handled certain network packets. An attacker could possibly     use this issue to execute arbitrary code. (CVE-2018-4013)

    It was discovered that liveMedia incorrectly handled certain network sessions. An attacker could possibly     use this issue to cause a denial of service. (CVE-2019-6256)

    It was discovered that liveMedia incorrectly handled certain RTSP streamings. An attacker could possiby     use this issue to cause a denial of service or other unspecified impact. (CVE-2019-7314)

    It was discovered that liveMedia incorrectly handled certain requests. An attacker could possibly use this     issue to obtain sensitive information. (CVE-2019-9215)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

This update for live555 fixes the following issues :

  - CVE-2019-9215: Malformed headers could have lead to     invalid memory access in the parseAuthorizationHeader     function. (boo#1127341)

  - CVE-2019-7314: Mishandled termination of an RTSP stream     after RTP/RTCP-over-RTSP has been set up could have lead     to a Use-After-Free error causing the RTSP server to     crash or possibly have unspecified other impact.
    (boo#1124159)

  - Update to version 2019.06.28, 

  - Convert to dynamic libraries (boo#1121995) :

  + Use make ilinux-with-shared-libraries: build the dynamic     libs instead of the static one.

  + Use make install instead of a manual file copy script:
    this also reveals that we missed quite a bit of code to     be installed before.

  + Split out shared library packages according the SLPP.

  - Use FAT LTO objects in order to provide proper static     library.

This update was imported from the openSUSE:Leap:15.1:Update update project.

The remote host is affected by the vulnerability described in GLSA-202005-06 (LIVE555 Media Server: Multiple vulnerabilities)

Multiple security issues were discovered in liveMedia, a set of C++ libraries for multimedia streaming which could result in the execution of arbitrary code or denial of service when parsing a malformed RTSP stream.

Multiple vulnerabilities have been discovered in liblivemedia, the LIVE555 RTSP server library :

CVE-2019-6256

liblivemedia servers with RTSP-over-HTTP tunneling enabled are vulnerable to an invalid function pointer dereference. This issue might happen during error handling when processing two GET and POST requests being sent with identical x-sessioncookie within the same TCP session and might be leveraged by remote attackers to cause DoS.

CVE-2019-7314

liblivemedia servers with RTSP-over-HTTP tunneling enabled are affected by a use-after-free vulnerability. This vulnerability might be triggered by remote attackers to cause DoS (server crash) or possibly unspecified other impact.

For Debian 8 'Jessie', these problems have been fixed in version 2014.01.13-1+deb8u2.

We recommend that you upgrade your liblivemedia packages.
