"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-5785-1 advisory.

  - In FreeRADIUS 3.0.x before 3.0.20, the EAP-pwd module used a global OpenSSL BN_CTX instance to handle all
    handshakes. This mean multiple threads use the same BN_CTX instance concurrently, resulting in crashes
    when concurrent EAP-pwd handshakes are initiated. This can be abused by an adversary as a Denial-of-
    Service (DoS) attack. (CVE-2019-17185)

  - Crash on unknown option in EAP-SIM (CVE-2022-41860)

  - Crash on invalid abinary data (CVE-2022-41861)

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