FFmpeg Multiple Vulnerabilities

Multiple vulnerabilities have been identified in FFmpeg, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise an application using the library.

1. An error within the "format_line()" function (libavutil/log.c) can be exploited to dereference a certain pointer.
2. An error within the "rle_unpack()" function (libavcodec/vmdav.c) can be exploited to cause an out of bounds memory access.
3. An error within the "mm_decode_inter()" function (libavcodec/mmvideo.c) can be exploited to cause an out of bounds memory access.
4. An integer overflow error within the "process_frame_obj()" function (libavcodec/sanm.c) can be exploited to cause an out of bounds memory access.
5. An error within the "cdg_decode_frame()" function (libavcodec/cdgraphics.c) can be exploited to cause an out of bounds memory access.
6. An error within the "gif_decode_frame()" function (libavcodec/gifdec.c) can be exploited to cause an out of bounds memory access.
