Vulnerability Title
FFmpeg 4.4 - 8.1.2 Out-of-Bounds Memory Access in ADX Audio Decoder
Vulnerability Description
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.

Vulnerability Title
FFmpeg 缓冲区错误漏洞
Vulnerability Description
FFmpeg是FFmpeg组织开源的一套可录制、转换以及流化音视频的完整解决方案。 FFmpeg 4.4版本至8.1.2版本存在缓冲区错误漏洞,该漏洞源于ADX音频解码器中libavcodec/adxdec.c存在越界内存访问问题,当mid-stream通道布局变化时,adx_decode_frame函数重新解析流头部但未能更新内部通道状态,导致后续解码操作使用过时的通道计数访问prev[]状态数组,可触发越界读取和越界写入。
