"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.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."

    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
