FFmpeg Multiple Vulnerabilities

Multiple vulnerabilities have been reported in FFmpeg, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise a user's system.

1. An error within the "avpriv_dv_produce_packet()" function (libavformat/dv.c) can be exploited to trigger an out-of-bounds memory read access and subsequently cause a crash.
2. An error within the "smacker_decode_header_tree()" function (libavcodec/smacker.c) can be exploited to trigger an out-of-bounds memory access.
3. An integer overflow error within the "smacker_read_packet()" function (libavformat/smacker.c) can be exploited to cause a heap-based buffer overflow.
4. An error exists within the "cin_read_frame_header()" function (libavformat/dsicin.c).
5. An error within the "g2m_load_cursor()" function (libavcodec/g2meet.c) can be exploited to corrupt memory.
6. An integer overflow error within the "mpc8_parse_seektable()" function (libavformat/mpc8.c) can be exploited to cause a heap-based buffer overflow.
7. A boundary error within the "decode_frame()" function (libavcodec/zmbv.c) can be exploited to cause a memory corruption.
8. An error within the "decode_wave_header()" function (libavcodec/shorten.c) can be exploited to cause a crash.

Successful exploitation of vulnerabilities #3, #4, #5, #6, and #7 may allow execution of arbitrary code.
