The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2855-1 advisory.

    Thilo Uttendorfer discovered that the Samba LDAP server incorrectly handled certain packets. A remote     attacker could use this issue to cause the LDAP server to stop responding, resulting in a denial of     service. This issue only affected Ubuntu 14.04 LTS, Ubuntu 15.04 and Ubuntu 15.10. (CVE-2015-3223)

    Jan Kasprzak discovered that Samba incorrectly handled certain symlinks. A remote attacker could use this     issue to access files outside the exported share path. (CVE-2015-5252)

    Stefan Metzmacher discovered that Samba did not enforce signing when creating encrypted connections. If a     remote attacker were able to perform a machine-in-the-middle attack, this flaw could be exploited to view     sensitive information. (CVE-2015-5296)

A remote attacker could     use this issue to cause the LDAP server to stop responding, resulting in a denial of service. This issue     only affected Ubuntu 14.04 LTS, Ubuntu 15.04 and Ubuntu 15.10. (CVE-2015-7540)

    Andrew Bartlett discovered that Samba incorrectly checked administrative privileges during creation of     machine accounts.
