Application crash via incorrect ID3v2 frame-size check
Published Jun 2, 2021 · Updated May 28, 2026
Out-of-bounds read in GStreamer Base Plug-ins before 1.18.4 allows local users to crash media applications via crafted ID3v2 tags. The id3v2_parse_frame parser checks the overall header frame size rather than the remaining frame_data_size before reading a four-byte data-length value. Exploitation requires an application to process a malicious media file; the resulting invalid read can terminate that application.
