"The remote Ubuntu 16.04 ESM / 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by
multiple vulnerabilities as referenced in the USN-5722-1 advisory.

    It was discovered that nginx incorrectly handled certain memory operations in the ngx_http_mp4_module
    module. A local attacker could possibly use this issue with a specially crafted mp4 file to cause nginx to
    crash, stop responding, or access arbitrary memory. (CVE-2022-41741, CVE-2022-41742)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
