📋 Description
FFmpeg through 9.0.2 contains an uninitialized memory disclosure vulnerability in the CineForm HD decoder that allows attackers to leak heap memory via unzeroed idwt_tmp buffers in libavcodec/cfhd.c. Attackers can supply a crafted CFHD file with an ImageHeight tag exceeding coded band heights, causing uninitialized heap bytes to be filtered into decoded video output.
