"The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by
multiple vulnerabilities as referenced in the USN-6809-1 advisory.

    It was discovered that BlueZ could be made to dereference invalid memory. An attacker could possibly use
    this issue to cause a denial of service. This issue only affected Ubuntu 22.04 LTS. (CVE-2022-3563)

    It was discovered that BlueZ could be made to write out of bounds. If a user were tricked into connecting
    to a malicious device, an attacker could possibly use this issue to cause a denial of service or execute
    arbitrary code. (CVE-2023-27349)

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

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
