"The VMware vCenter Server installed on the remote host is version 5.5
prior to Update 2d. It is, therefore, affected by multiple
vulnerabilities in the included OpenSSL library :

  - An error exists related to DTLS SRTP extension handling
    and specially crafted handshake messages that can allow
    denial of service attacks via memory leaks.
    (CVE-2014-3513)

  - An error exists related to the way SSL 3.0 handles
    padding bytes when decrypting messages encrypted using
    block ciphers in cipher block chaining (CBC) mode.
    Man-in-the-middle attackers can decrypt a selected byte
    of a cipher text in as few as 256 tries if they are able
    to force a victim application to repeatedly send the
    same data over newly created SSL 3.0 connections. This
    is also known as the 'POODLE' issue. (CVE-2014-3566)

  - An error exists related to session ticket handling that
    can allow denial of service attacks via memory leaks.
    (CVE-2014-3567)

  - An error exists related to the build configuration
    process and the 'no-ssl3' build option that allows
    servers and clients to process insecure SSL 3.0
    handshake messages. (CVE-2014-3568)");
