Sources and claim methodology

Upstream source description

FFmpeg through 9.0.2 contains a NULL pointer dereference vulnerability in the Motion Pixels decoder because mp_decode_frame() ignores init_get_bits() failure. Attackers supplying a roughly 2^28-byte packet through the libavcodec API overflow the bit count, causing reads from a NULL buffer that crash the process.
