FFmpeg through 9.0.2 contains a heap buffer overflow vulnerability in libavcodec/exrenc.c that allows attackers to corrupt heap memory when encode_scanline_rle() processes frames taller than the encoder height. Attackers can supply crafted input whose resolution grows mid-stream, transcoded to OpenEXR with RLE compression, to write pointers past the scanline array and crash the application.
