"The remote Debian host is missing a security update.");
  script_set_attribute(attribute:"description", value:
"The RTSP connection parser in the base GStreamer packages version 1.0,
which is a streaming media framework, was vulnerable against an
heap-based buffer overflow by sending a longer than allowed session id
in a response and including a semicolon to change the maximum length.
This could result in a remote code execution.

For Debian 8 'Jessie', this problem has been fixed in version
1.4.4-2+deb8u2.

We recommend that you upgrade your gst-plugins-base1.0 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.");
