The ff_dwt_decode function in libavcodec/jpeg2000dwt.c in FFmpeg before 2.8.4 does not validate the number of decomposition levels before proceeding with Discrete Wavelet Transform decoding, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted JPEG 2000 data.

Security readout for executives and security teams

This is an older FFmpeg JPEG 2000 decoding flaw. A specially crafted JPEG 2000 file could crash software that decodes it, causing denial of service. The public record says other unspecified impact may be possible, but provides no confirmed details. Exposure is most likely in applications, services, or pipelines that accept and decode untrusted JPEG 2000 media using FFmpeg before 2.8.4 or affected distro libav packages. Treat this as a moderate operational risk for media-processing systems. Prioritize remediation where public uploads, automated file conversion, or external media feeds reach vulnerable FFmpeg or libav components. Mitigation focus: Upgrade FFmpeg to 2.8.4 or later where vendor guidance confirms the fix.; Apply relevant distribution security updates for libav or FFmpeg packages.; If upgrades are delayed, restrict untrusted JPEG 2000 ingestion or decoding..
