CVE-2023-6604 Details
Description
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.
A denial-of-service vulnerability has been identified in FFmpeg versions 2.0 (at least) through 6.0 (latest). This issue arises in the HLS (HTTP Live Streaming) XBIN demuxer, where the absence of proper input format validation allows arbitrary data to be processed as XBIN-formatted. This exploitation leads to a significant increase in CPU usage during transcoding and creates excessively large output files, causing degraded performance. The vulnerability could be triggered by crafting an HLS playlist that bypasses file extension checks, directing FFmpeg to demux non-XBIN data as XBIN, which is then amplified into a larger file.
To address this vulnerability, the XBIN demuxer should only be activated if the input file extension matches a known XBIN extension, such as .XB.
