This vulnerability allows arbitrary HTTP GET requests to be made on behalf of the machine running FFmpeg via a crafted DASH playlist containing malicious URLs. CVE-2023-6604: A flaw was found in FFmpeg. This vulnerability allows unexpected additional CPU load and storage consumption, potentially leading to degraded performance or denial of service via the demuxing of arbitrary data as XBIN-formatted data without proper format validation. CVE-2023-6602: flaw was found in FFmpeg's TTY Demuxer. This vulnerability allows possible data exfiltration via improper parsing of non-TTY-compliant input files in HLS playlists.
