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 "pcx_decode_frame()" function (libavcodec/pcx.c) can be exploited to cause a crash.
2. An error within the "xan_decode_init()" function (libavcodec/xxan.c) can be exploited to cause an out of bounds write memory access.
3. An error within the "pcx_decode_frame()" function (libavcodec/pcx.c) can be exploited to trigger an infinite loop.
4. An error within the "png_decode_idat()" function (libavcodec/pngdec.c) can be exploited to trigger an infinite loop.
5. An error within the "bfi_read_packet()" function (libavformat/bfi.c) can be exploited to trigger a division-by-zero exception.
6. An error within the "ff_get_wav_header()" function (libavformat/riffdec.c) can be exploited to trigger a division-by-zero exception.
7. An error within the "read_header()" function (libavformat/mvi.c) can be exploited to trigger a division-by-zero exception.
8. A boundary error within the "decode_element()" function (libavcodec/alac.c) can be exploited to cause an out of bounds write memory access.
9. An error within the "xwma_read_header()" function (libavformat/xwma.c) can be exploited to trigger a division-by-zero exception.
10. An error within the "read_gab2_sub()" function (libavformat/avidec.c) can be exploited to cause an out of bounds read memory access.
11. An error within the "vqf_read_header()" function (libavformat/vqf.c) can be exploited to cause a crash.

Successful exploitation of the vulnerabilities #2 and #8 may allow execution of arbitrary code.
