FFmpeg through 9.0.2 contains a heap overflow vulnerability in libavcodec/qsvenc.c that allows attackers to corrupt memory by reusing an undersized pooled QSVFrame buffer when input dimensions increase. Attackers can supply crafted input whose resolution grows mid-stream, transcoded with Intel Quick Sync encoders without rescaling, to crash the application or corrupt heap memory.
