The fix is mentioned in the CVE (https://urldefense.com/v3/__https://nvd.nist.gov/vuln/detail/CVE-2021-38171__;!!GryZGb6B1VCs0SfC!STlY1eVFcY7A-cEivbXk3VLtyrGJo5LDgP5i-zHeUlfLdy3k6v7Aff7siDm3Ovc$ ):
It was ported to the 4.4 branch here:
and that is contained in release 4.4.1, as far as I can tell (by "git tag --contains fb993619d1035fa9646506925ea70fb122038999").
So the CVE refers to version 4.4, and version 4.4.1 fixes this and is therefore not affected, AFAICT.
You'll have to have your security team check 4.4.1. You may need to check each CVE separately (they mention "multiple known vulnerabilities"). If in doubt, disable the affected feature (as in this case: the ADTS muxer).
Hope this helps,
