Description
FFmpeg through 9.0.2 contains a heap buffer overflow vulnerability in libavcodec/videotoolboxenc.c that copies frames larger than encoder dimensions into undersized CVPixelBuffers. Attackers can supply crafted input whose resolution grows mid-stream, transcoded with VideoToolbox encoders without rescaling, to crash the application or corrupt memory.
