The vulnerability exists in the decode_init function in libavcodec/utvideodec.c due to insufficient input validation. A remote attacker can trick the victim into opening a specially crafted AVI file that submits malicious input, trigger a out-of-bounds read and cause the service to crash.
2) Assertion violation (CVE-ID: CVE-2018-12458)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to improper integer type in the mpeg4_encode_gop_header function in libavcodec/mpeg4videoenc.c. A remote attacker can supply specially crafted AVI file to MPEG4, trick the victim into converting it, trigger assertion violation and cause the service to crash.
3) Out-of-bounds read (CVE-ID: CVE-2018-13300)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to improper argument (AVCodecParameters) passed to the avpriv_request_sample function in the handle_eac3 function in libavformat/movenc.c. A remote attacker can supply specially crafted AVI file to MPEG4, trick the victim into converting it, trigger out-of-bounds read and cause the service to crash or possibly access arbitrary data
4) Out-of-bounds read (CVE-ID: CVE-2018-13302)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to improper handling of frame types of multiple independent substreams in the handle_eac3 function in libavformat/movenc.c in EAC3_FRAME_TYPE_INDEPENDENT). A remote attacker can supply specially crafted AVI file to MPEG4, trick the victim into converting it, trigger out-of-bounds read and cause the service to crash.
