USN-3958-1: GStreamer Base Plugins vulnerability
29 April 2019

gst-plugins-base0.10, gst-plugins-base1.0 vulnerability
A security issue affects these releases of Ubuntu and its derivatives:

  o Ubuntu 18.10
  o Ubuntu 18.04 LTS
  o Ubuntu 16.04 LTS


GStreamer Base Plugins could be made to crash or run programs if it received
specially crafted network traffic.

Software Description

  o gst-plugins-base1.0 - GStreamer plugins
  o gst-plugins-base0.10 - GStreamer plugins


It was discovered that GStreamer Base Plugins did not correctly handle certain
malformed RTSP streams. If a user were tricked into opening a crafted RTSP
stream with a GStreamer application, an attacker could cause a denial of
service via application crash, or possibly execute arbitrary code.
