CVE-2024-47545

Application crash via unchecked strf size subtraction

Published Dec 11, 2024 · Updated Nov 3, 2025

Out-of-bounds read in GStreamer before 1.24.10 allows local users to crash applications by processing a crafted MP4 or MOV file. The qtdemux_parse_trak strf handler subtracts 40 from an input-derived size without first ensuring that the value is at least 40, causing gst_buffer_fill to pass an enormous length to memcpy. Processing a malformed track is required; the documented outcome is an out-of-bounds read of up to 4 GB or a consuming-application crash, with no reported code execution.
