vulnerabilities.");
  script_set_attribute(attribute:"description", value:
"The version of Oracle Secure Global Desktop installed on the remote
host is 4.63, 4.71, or 5.2 and is missing a security patch from the
July 2016 Critical Patch Update (CPU). It is, therefore, affected by
the following vulnerabilities :

  - An integer overflow condition exists in the X Server
    subcomponent in the read_packet() function due to
    improper validation of user-supplied input when
    calculating the amount of memory required to handle
    returned data. A remote attacker can exploit this to
    cause a denial of service condition or the execution of
    arbitrary code. Note that this vulnerability only
    affects versions 4.71 and 5.2. (CVE-2013-2064)

  - A carry propagating flaw exists in the OpenSSL
    subcomponent in the x86_64 Montgomery squaring
    implementation that may cause the BN_mod_exp() function
    to produce incorrect results. An attacker can exploit
    this to obtain sensitive information regarding private
    keys. (CVE-2015-3193)

  - A NULL pointer dereference flaw exists in the OpenSSL
    subcomponent in file rsa_ameth.c when handling ASN.1
    signatures that use the RSA PSS algorithm but are
    missing a mask generation function parameter. A remote
    attacker can exploit this to cause the signature
    verification routine to crash, leading to a denial of
    service. (CVE-2015-3194)

  - A key disclosure vulnerability exists in the OpenSSL
    subcomponent due to improper handling of cache-bank
    conflicts on the Intel Sandy-bridge microarchitecture.
    An attacker can exploit this to gain access to RSA key
    information. (CVE-2016-0702)

  - A NULL pointer dereference flaw exists in the OpenSSL
    subcomponent in the BN_hex2bn() and BN_dec2bn()
    functions. A remote attacker can exploit this to trigger
    a heap corruption, resulting in the execution of
    arbitrary code. (CVE-2016-0797)

  - Multiple memory corruption issues exist in the OpenSSL
    subcomponent that allow a remote attacker to cause a
    denial of service condition or the execution of
    arbitrary code. (CVE-2016-0799)

  - A heap buffer overflow condition exists in the OpenSSL
    subcomponent in the EVP_EncodeUpdate() function within
    file crypto/evp/encode.c that is triggered when handling
    a large amount of input data. An unauthenticated, remote
    attacker can exploit this to cause a denial of service
    condition. (CVE-2016-2105)

  - Multiple flaws exist in the OpenSSL subcomponent in the
    aesni_cbc_hmac_sha1_cipher() function in file
    crypto/evp/e_aes_cbc_hmac_sha1.c and the
    aesni_cbc_hmac_sha256_cipher() function in file
    crypto/evp/e_aes_cbc_hmac_sha256.c that are triggered
    when the connection uses an AES-CBC cipher and AES-NI
    is supported by the server. A man-in-the-middle attacker
    can exploit these to conduct a padding oracle attack,
    resulting in the ability to decrypt the network traffic.
    (CVE-2016-2107)

  - An unspecified flaw exists in the OpenSSL subcomponent
    that allows a remote attacker to execute arbitrary
    code. (CVE-2016-3613)");
