The version of F5 Networks BIG-IP installed on the remote host is prior to 14.1.4.4 / 15.1.4.1 / 16.1.2. It is, therefore, affected by a vulnerability as referenced in the K42910051 advisory.

  - The X.509 GeneralName type is a generic type for representing different types of names. One of those name     types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different     instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both     GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a     possible denial of service attack. OpenSSL itself uses the GENERAL_NAME_cmp function for two purposes: 1)     Comparing CRL distribution point names between an available CRL and a CRL distribution point embedded in     an X509 certificate 2) When verifying that a timestamp response token signer matches the timestamp     authority name (exposed via the API functions TS_RESP_verify_response and TS_RESP_verify_token) If an     attacker can control both items being compared then that attacker could trigger a crash. For example if     the attacker can trick a client or server into checking a malicious certificate against a malicious CRL     then this may occur. Note that some applications automatically download CRLs based on a URL embedded in a     certificate. This checking happens prior to the signatures on the certificate and CRL being verified.
    OpenSSL's s_server, s_client and verify tools have support for the -crl_download option which implements     automatic CRL downloading and this attack has been demonstrated to work against those tools. Note that an     unrelated bug means that affected versions of OpenSSL cannot parse or construct correct encodings of     EDIPARTYNAME. However it is possible to construct a malformed EDIPARTYNAME that OpenSSL's parser will     accept and hence trigger this attack. All OpenSSL 1.1.1 and 1.0.2 versions are affected by this issue.
    Other OpenSSL releases are out of support and have not been checked. Fixed in OpenSSL 1.1.1i (Affected     1.1.1-1.1.1h). Fixed in OpenSSL 1.0.2x (Affected 1.0.2-1.0.2w). (CVE-2020-1971)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
