Vendor Workaround
There is no complete mitigation for applications that continue to deserialize untrusted GStreamer caps or structure strings. Restrict access to network-facing GStreamer Data Protocol receivers to trusted peers, and avoid passing externally supplied strings to gst_caps_from_string() or gst_structure_from_string() until an update is available. These measures reduce exposure only where the application can control those input paths.

| Description | A use-after-free flaw was found in GStreamer core buffer value deserialization. When crafted serialized buffer data contains an invalid character, an error path frees a mapped buffer before unmapping it. An application that parses untrusted caps or structure data could crash; a network-facing GStreamer Data Protocol receiver can process such data without user interaction. Further impact has not been established. | |
