"The version of OpenSSL installed on the remote host is prior to 1.0.0n. It is, therefore, affected by multiple
vulnerabilities as referenced in the 1.0.0n advisory.

  - The ssl3_send_client_key_exchange function in s3_clnt.c in OpenSSL 0.9.8 before 0.9.8zb, 1.0.0 before
    1.0.0n, and 1.0.1 before 1.0.1i allows remote DTLS servers to cause a denial of service (NULL pointer
    dereference and client application crash) via a crafted handshake message in conjunction with a (1)
    anonymous DH or (2) anonymous ECDH ciphersuite. (CVE-2014-3510)

  - Race condition in the ssl_parse_serverhello_tlsext function in t1_lib.c in OpenSSL 1.0.0 before 1.0.0n and
    1.0.1 before 1.0.1i, when multithreading and session resumption are used, allows remote SSL servers to
    cause a denial of service (memory overwrite and client application crash) or possibly have unspecified
    other impact by sending Elliptic Curve (EC) Supported Point Formats Extension data. (CVE-2014-3509)

  - The OBJ_obj2txt function in crypto/objects/obj_dat.c in OpenSSL 0.9.8 before 0.9.8zb, 1.0.0 before 1.0.0n,
    and 1.0.1 before 1.0.1i, when pretty printing is used, does not ensure the presence of '\0' characters,
    which allows context-dependent attackers to obtain sensitive information from process stack memory by
    reading output from X509_name_oneline, X509_name_print_ex, and unspecified other functions.
    (CVE-2014-3508)

  - Memory leak in d1_both.c in the DTLS implementation in OpenSSL 0.9.8 before 0.9.8zb, 1.0.0 before 1.0.0n,
    and 1.0.1 before 1.0.1i allows remote attackers to cause a denial of service (memory consumption) via
    zero-length DTLS fragments that trigger improper handling of the return value of a certain insert
    function. (CVE-2014-3507)

  - d1_both.c in the DTLS implementation in OpenSSL 0.9.8 before 0.9.8zb, 1.0.0 before 1.0.0n, and 1.0.1
    before 1.0.1i allows remote attackers to cause a denial of service (memory consumption) via crafted DTLS
    handshake messages that trigger memory allocations corresponding to large length values. (CVE-2014-3506)

  - Double free vulnerability in d1_both.c in the DTLS implementation in OpenSSL 0.9.8 before 0.9.8zb, 1.0.0
    before 1.0.0n, and 1.0.1 before 1.0.1i allows remote attackers to cause a denial of service (application
    crash) via crafted DTLS packets that trigger an error condition. (CVE-2014-3505)

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