Description
FFmpeg through 9.0.2 contains an integer overflow vulnerability in wavpack_encode_init() in libavcodec/wavpackenc.c that causes an infinite loop when computing block size from sample rate and channel count. Attackers can supply a crafted audio file, such as a WAV header declaring a huge sample rate with many channels, to hang applications transcoding to WavPack.
