"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.

block directly from the DLA security advisory. Tenable has attempted

introducing additional issues.");
