"The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in
the USN-3719-3 advisory.

    USN-3719-1 fixed vulnerabilities in Mutt. Unfortunately, the fixes were not correctly applied to the
    packaging for Mutt in Ubuntu 16.04 LTS. This update corrects the oversight.

    We apologize for the inconvenience.

    Original advisory details:

    It was discovered that Mutt incorrectly handled certain requests.

    An attacker could possibly use this to execute arbitrary code.

    (CVE-2018-14350, CVE-2018-14352, CVE-2018-14354, CVE-2018-14359,

    CVE-2018-14358, CVE-2018-14353 ,CVE-2018-14357)

    It was discovered that Mutt incorrectly handled certain inputs.

    An attacker could possibly use this to access or expose sensitive

    information. (CVE-2018-14355, CVE-2018-14356, CVE-2018-14351,

    CVE-2018-14362, CVE-2018-14349)

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
