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

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

  - FFmpeg <=4.3 contains a buffer overflow vulnerability in libavcodec through a crafted file that may lead
    to remote code execution. (CVE-2021-30123)

    could let a remote malicious user cause a Denial of Service (CVE-2020-21041)

  - A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the
    ff_v4l2_m2m_create_context function in v4l2_m2m.c. (CVE-2020-22038)

    value, which is a necessary step because the second argument to init_get_bits can be crafted.
    (CVE-2021-38171)
