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.
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
