"The version of F5 Networks BIG-IP installed on the remote host is prior to 15.1.10 / 16.1.4 / 17.1.0.1. It is,
therefore, affected by a vulnerability as referenced in the K000132946 advisory.

  - The public API function BIO_new_NDEF is a helper function used for streaming ASN.1 data via a BIO. It is
    primarily used internally to OpenSSL to support the SMIME, CMS and PKCS7 streaming capabilities, but may
    also be called directly by end user applications. The function receives a BIO from the caller, prepends a
    new BIO_f_asn1 filter BIO onto the front of it to form a BIO chain, and then returns the new head of the
    BIO chain to the caller. Under certain conditions, for example if a CMS recipient public key is invalid,
    the new filter BIO is freed and the function returns a NULL result indicating a failure. However, in this
    case, the BIO chain is not properly cleaned up and the BIO passed by the caller still retains internal
    pointers to the previously freed filter BIO. If the caller then goes on to call BIO_pop() on the BIO then
    a use-after-free will occur. This will most likely result in a crash. This scenario occurs directly in the
    internal function B64_write_ASN1() which may cause BIO_new_NDEF() to be called and will subsequently call
    BIO_pop() on the BIO. This internal function is in turn called by the public API functions
    PEM_write_bio_ASN1_stream, PEM_write_bio_CMS_stream, PEM_write_bio_PKCS7_stream, SMIME_write_ASN1,
    SMIME_write_CMS and SMIME_write_PKCS7. Other public API functions that may be impacted by this include
    i2d_ASN1_bio_stream, BIO_new_CMS, BIO_new_PKCS7, i2d_CMS_bio_stream and i2d_PKCS7_bio_stream. The OpenSSL
    cms and smime command line applications are similarly affected. (CVE-2023-0215)

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