In libavcodec in FFmpeg 4.0.1, improper maintenance of the consistency between the context profile field and studio_profile in libavcodec may trigger an assertion failure while converting a crafted AVI file to MPEG4, leading to a denial of service, related to error_resilience.c, h263dec.c, and mpeg4videodec.c.

In FFmpeg 4.0.1, a missing check for failure of a call to init_get_bits8() in the avpriv_ac3_parse_header function in libavcodec/ac3_parser.c may trigger a NULL pointer dereference while converting a crafted AVI file to MPEG4, leading to a denial of service.

In FFmpeg 4.0.1, improper handling of frame types (other than EAC3_FRAME_TYPE_INDEPENDENT) that have multiple independent substreams in the handle_eac3 function in libavformat/movenc.c may trigger an out-of-array access while converting a crafted AVI file to MPEG4, leading to a denial of service or possibly unspecified other impact.

In FFmpeg 4.0.1, due to a missing check of a profile value before setting it, the ff_mpeg4_decode_picture_header function in libavcodec/mpeg4videodec.c may trigger a NULL pointer dereference while converting a crafted AVI file to MPEG4, leading to a denial of service.

In FFmpeg 3.2 and 4.0.1, an improper argument (AVCodecParameters) passed to the avpriv_request_sample function in the handle_eac3 function in libavformat/movenc.c may trigger an out-of-array read while converting a crafted AVI file to MPEG4, leading to a denial of service and possibly an information disclosure.
