critical Tenable Cloud Security Plugin ID 404325

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- adts_decode_extradata in libavformat/adtsenc.c in FFmpeg 4.4 does not check the init_get_bits return

(CVE-2021-38171)

- FFmpeg 4.2 is affected by a Divide By Zero issue via libavcodec/aacpsy.c, which allows a remote malicious
user to cause a Denial of Service. (CVE-2020-20446)

- FFmpeg 4.2 is affected by null pointer dereference passed as argument to libavformat/aviobuf.c, which
could cause a Denial of Service. (CVE-2020-20450)

- FFmpeg 4.2 is affected by a Divide By Zero issue via libavcodec/aaccoder, which allows a remote malicious
user to cause a Denial of Service (CVE-2020-20453)

- Buffer Overflow vulnerability in FFmpeg 4.2 in mov_write_video_tag due to the out of bounds in
libavformat/movenc.c, which could let a remote malicious user obtain sensitive information, cause a Denial
of Service, or execute arbitrary code. (CVE-2020-22015)
