    Please review the referenced CVE identifiers for details.
  Workaround :

    There is no known workaround at this time.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - OpenConnect through 8.08 mishandles negative return values from X509_check_ function calls, which might     assist attackers in performing man-in-the-middle attacks. (CVE-2020-12105)

Note that Nessus relies on the presence of the package as reported by the vendor.
