"The remote Ubuntu 18.04 ESM host has packages installed that are affected by a vulnerability as referenced in the
USN-4836-1 advisory.

  - An issue was discovered in the Ldap component in Symfony 2.8.x before 2.8.37, 3.3.x before 3.3.17, 3.4.x
    before 3.4.7, and 4.0.x before 4.0.7. It allows remote attackers to bypass authentication by logging in
    with a null password and valid username, which triggers an unauthenticated bind. NOTE: this issue exists
    because of an incomplete fix for CVE-2016-2403. (CVE-2018-11407)

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