Summary

FFmpeg versions 4.4 through 8.1.2 contain an out-of-bounds memory access vulnerability in the ADX audio decoder. An attacker can supply a crafted ADX or AAX audio file with a mid-stream channel layout change, causing the use of a stale channel count and out-of-bounds memory access.

Risk Assessment

The vulnerability can lead to application crashes, data leakage, or potentially code execution by an attacker in the context of the FFmpeg process.

Recommendation

Upgrade FFmpeg to version 8.2 or later, which includes a fix for this vulnerability.

Original NVD description (English source)

FFmpeg versions 4.4 through 8.1.2 contain an out-of-bounds memory access vulnerability in the ADX audio decoder within libavcodec/adxdec.c that allows attackers to trigger both out-of-bounds reads and writes by supplying a crafted ADX or AAX audio file with a mid-stream channel layout change. When AV_PKT_DATA_NEW_EXTRADATA side data is received mid-stream, the adx_decode_frame function re-parses the stream header but fails to update the internal channel state, causing subsequent decoding operations to access the prev[] state array using a stale channel count.
