FFmpeg through 9.0.2 contains a heap buffer overflow in ff_libwebp_get_frame() in libwebpenc_common.c that lets attackers corrupt memory when cr_threshold is set. Attackers can supply crafted media that increases resolution mid-stream, causing memcpy() to write pixel data past the stale reference frame and crash applications.
