Multiple use-after-free vulnerabilities in the (1) gst_mini_object_unref, (2) gst_tag_list_unref, and (3) gst_mxf_demux_update_essence_tracks functions in GStreamer before 1.10.3 allow remote attackers to cause a denial of service (crash) via vectors involving stream tags, as demonstrated by 02785736.mxf.

From the Ubuntu Security Team

Hanno Böck discovered that GStreamer Bad Plug-ins incorrectly handled vectors involving stream tags. A remote attacker could exploit this with a crafted MXF file to cause GStreamer to crash, resulting in a denial of service.
