CVE-2024-47606

Code execution via Theora extension integer underflow

Published Dec 11, 2024 · Updated Nov 3, 2025

Integer underflow in GStreamer before 1.24.10 allows attackers to execute code when a crafted MP4 or MOV file is processed. qtdemux_parse_theora_extension subtracts eight from an undersized signed length, which wraps through unsigned allocation arithmetic and leaves an undersized heap buffer for gst_buffer_fill. Processing the file is required; the overwrite can corrupt GstMapInfo and hijack an allocator unmap function pointer, causing a crash or code execution in the media application's context.
