"The version of Symantec Encryption Management Server running on the
remote host is 3.3.2 prior to version 3.3.2 MP12. It is, therefore, 
affected by multiple vulnerabilities :

  - An unspecified flaw in the LDAP service allows a remote
    attacker, via a crafted LDAP request, to gather
    sensitive information about valid administrator accounts
    on the server. (CVE-2015-8148)

  - A denial of service exists in the LDAP service due to a
    failure to properly validate user-supplied input. An
    unauthenticated, remote attacker can exploit this, via
    crafted request packets, to cause corrupted memory block
    headers, leading to a SIGSEGV fault and resulting in a
    service halt. (CVE-2015-8149)

  - An unspecified flaw exists that is related to scheduling
    commands to run via existing batch files, which normally
    run with root privileges. A local attacker can exploit
    this to gain elevated privileges on the server.
    (CVE-2015-8150)

  - A command injection vulnerability exists in the web user
    interface due to a failure to properly sanitize certain
    user-supplied input fields. An authenticated, remote
    attacker can exploit this to run arbitrary commands with
    elevated privileges on the underlying operating system.
